What does BFP stand for in fertility?
In the world of fertility and conception, BFP is likely the thing you’ve been looking forward to most on your journey to getting pregnant. BFP simply means big fat positive, referring to a pregnancy test result. You’ll see the term thrown around often in mom-to-be and fertility message boards and in online and offline communities of current and aspiring moms. The “BF” portion, meaning “big fat,” does not refer to a specific kind of positive result, but rather emphasizes the magnitude of seeing a positive result, no matter how faint the line may be.
When should I expect a BFP?
At eighteen days following ovulation, the accuracy of detecting a positive pregnancy result is at about 99%. Here’s how accurate your search for a BFP will be if you take your pregnancy test at various times:
10 days after ovulation: 35%
11 days after ovulation: 51%
12 days after ovulation: 62%
13 days after ovulation: 68%
14 days after ovulation: 74%
15 days after ovulation: 80%
16 days after ovulation: 88%
17 days after ovulation: 92%
18 days after ovulation: 99%
You can see from these numbers why it’s generally advised to wait at least two weeks after ovulation to begin testing for pregnancy. Sound like a long time? Technically, you may see a BFP as soon as six days after conception, and the generally accepted norm seems to be 10 days, but that’s simply not the case. These deflated numbers have been perpetuated as normal because those who receive a BFP early are more likely to shout it from the rooftops than those who get their BFP on a normal schedule or even late.
All this is to say that there’s really no reason to take a pregnancy test before two weeks after ovulating. If you decide to do it sooner, start at 10 days and do not give up until at least 18 days have passed. Missing a period is your best signal to take a pregnancy test in hopes of seeing a BFP.
What is the earliest BFP you can get?
While some women report getting a positive early pregnancy test result as soon as six days post-ovulation, that is very unlikely. The anticipation is killer, but there is not sense in wasting money on pregnancy tests until at least 10 days following the hopeful conception date. Waiting until the first day of your missed period is most likely to yield accurate results the first time around.
Symptoms before BFP
Missing your period is the most common “symptom” woman experience before taking a pregnancy test and getting a BFP. However, there are some early pregnancy symptoms that may show themselves even before your missed period, and before a pregnancy test comes back positive.
Even small changes in the body may set off alarm bells that you’re in fact pregnant even before a BFP shows up on a test. Women who notice these symptoms usually feel very in-tune with their body and notice even slight hormonal changes throughout their regular menstrual cycles. These early symptoms may present as early as a week before there are enough pregnancy hormones present to yield a BFG.
Do not be disheartened if you feel cramping following ovulation! When the fertilized egg or embryo implants in the uterus early on, it can cause some women to experience cramping. Implantation takes place 8–10 days post-ovulation, or 4–6 days before your next period. Many women experience regular menstrual cramps during this same period, so you may not be able to tell the difference between period and pregnancy cramps. If you feel cramping, you should definitely take a pregnancy test if you miss your period as it very well may be cramping from pregnancy.
You should also not lose all hope of pregnancy if you experience spotting a few days after ovulating. Many women experience spotting early on in pregnancy, which is said to be due to the fertilized egg implanting in the uterus (like cramping). Pregnancy spotting usually last up to three days and is light pink or brown in color. You may experience spotting with abdominal cramps and still be on your way to a BFP.
You’ve heard about pregnant women constantly needing to pee, but that very true stereotype is usually reserved for moms-to-be with fully showing bellies. However, early hormonal changes can also cause this pregnancy symptom early on by increasing the speed of blood flow to your kidneys. This causes the bladder to fill up more quickly, making you need to pee more often. Some women notice this sign even before a missed period all the way through the pregnancy.
Most women do not experience morning sickness until six weeks into being pregnant, but some feel this symptom as early as one week following conception, which is a full week before your missed period and a likely BFP. Again, hormone fluctuations are to blame. You may experience nausea with or without vomiting and it may be present all day long.
Fatigue can come on suddenly and be debilitating, though temporary. Rising progesterone levels are at work when you feel sudden bouts of complete exhaustion. Many women chalk up fatigue during this time to falling ill, but it may be an early sign of a BFP in your near future.
Aversion to smells
The aversion to smells comes on rapidly and is most likely to be noticed first in the kitchen. Foods that are common and did not bother you before may become unbearable. This is a long known and tell tale sign of being pregnant and can present very early on after conception.
Metallic taste in mouth
A metal taste in the mouth is another early pregnancy sign, which usually occurs alongside aversion to smells. Many say it tastes like they’ve been sucking on pennies. Many report this symptom going away after the first trimester, but some experience it until delivery.
Breasts may become tender as progesterone levels rise in the body. Many women experience this each month before their period, but the phenomenon experienced before a BFP is usually significantly more intense.
Areolas are known to become darker during pregnancy due to HCG hormone levels. Some women notice this darkening happening almost immediately after conception.
Can you get a BFP after your period?
Getting your period may not be the sign that a BFP is at least another month away. You may be experiencing early pregnancy symptoms (cramping, spotting) that you mistake for your period. Wait a few days and take a pregnancy test, especially if you are feeling any other early pregnancy symptoms.
What does a BFP after period mean?
A BFP after getting your period could mean you mistook early pregnancy signs for your period.
What is a faint BFP?
As mentioned above, BFP does not refer to a certain kind of positive pregnancy result. A faint BFP means that a positive result is displaying as a faint line, plus sign, etc on your pregnancy test strips. rather than something darker. Waiting a few days and taking another pregnancy test will help you get more definitive results.
BFP with low basal body temperature
Basal body temperature (BBT) refers to your lowest body temperature when at rest. It fluctuates with your menstrual cycle and is used by many to estimate ovulation. Many women who track BBT report sustained higher BBT following conception. If you experience a BFP and low-range BBT, do not be alarmed—the pregnancy test is the more accurate measuring tool and other factors can affect your BBT. If your BBT drops above or below normal, you should consult your doctor.
Is it BFP or AF (period) symptoms?
It can be hard to determine whether your body is experiencing early pregnancy or simply its normal visit from AF as cramping and spotting are common in both. Early pregnancy spotting tends to only last three days, which can help indicate which your experiencing. Cramps from pregnancy may present themselves earlier in the month than you’re used to.
Can you get a BFP before implantation?
It is not possible to get a BFP before implantation occurs. That’s because the implantation itself is what causes a rise in HGC, which is the hormone measure by tests to determine if you’re pregnant.
Can BFP be false?
Though a false positive is less likely than a false negative, a BFP can be false. The blood test performed by your doctor can corroborate results of an at home pregnancy test.
Can early BFP mean twins?
While the correlation has not been scientifically proven, some women have found a connection with early positive pregnancy results and having twins. There is absolutely no way of knowing that your early BFP is an indicator of twins until you’re ready for an ultrasound.
Does an early BFP mean girl and late BFP mean boy?
While some like to claim they do, timing of your BFP does not indicate the sex of your future child.
Does a late BFP mean an unsuccessful pregnancy?
A late BFP is a relative term and does not by any means indicate that your pregnancy will be unsuccessful. You may get a positive result later than expected for a few reasons:
- Ovulation did not occur exactly when you thought it did
- The test used is not as sensitive as others
- Your HCG levels hadn’t risen high enough yet
Is late BFP a sign of increased risk?
A late positive pregnancy results is not a sign of increased risk. There are many reasons a BFP may come “late,” most of which include human error or natural body differences.
