Earliest BFP

RazzyRN · November 2013

What is the earliest you ladies received a BFP?

Stephdb · November 2013

27 days after my period began

Ashw1990 · November 2013

4 days before AF was due. That was with a FRER.

Erica314 · November 2013

CD 27 or 11 DPO. I got a super squinter on 10 DPO but I didn't believe it until I saw a clear line the next day.

This kind of question is hard to answer because if you are not tracking your ovulation (with OPKs and temping), the responses here are going to be relatively meaningless for you.

In my case, CD34, which was 9DPO.

I just started temping, was just wondering if anybody had any BFP before the end of the 2WW

Ah, ok. How early you see a bfp depends on when implantation occurs but I've seen a lot of bfps posted here before 14 dpo.

Good luck!

8DPO. Usually I get them around 9 or 10. I would have gotten it at 7DPO with that pregnancy though bc I had a blood test that day and my beta was 79 at 7DPO.

Earliest reasonable BFP, assuming you know the exact time of ovulation and fertilization is 8days past fertilization. The first 5-6 days of the embryos life are spent dividing and traveling down the Fallopian tubes into the uterus. Day 6-7ish is implantation, at which point HCG production begins. If you're lucky, 24 hours after implantation there might be enough HCG for the first response tests to pick up.

Of course, unless you're doing a fertility treatment that involves introducing the egg and sperm in a Petri dish- you have a minimum of 1-2 days of uncertainty. Fertilization doesn't occur at the same instant as ovulation, sometimes the trip down the Fallopian tube takes an extra day, sometimes it takes an extra day before the embryo implants, sometimes HCG production is sluggish and it takes 48 instead of 24 hours to get a positive. And all that assumes that ovulation actually occurred on the day you guess

So its really not worth bothering to test before 10dpo in a typical cycle- but it's certainly possible to get a positive before the end of the 2ww.

2 days before AF was due .. but the second line was SO faint, I almost threw the first test out, thinking it was negative, until I took a second look and realized it wasn't!

jenandtim828 · November 2013

CD 18, 10 dpo

Mjl0405 · November 2013

8 dpo

Honeydewchestnut · November 2013

8 DPO this time around on a wondofo. It was so light, but definitely there.

If you know how to read your charts and have been charting for a few cycles, then you'll see the pregnancy in the chart before you can get a positive test result. In a normal cycle, you ovulate, your temp spikes, and then it tapers back down. When you conceive, you ovulate, your temp spikes, and it stays up, doesn't come back down. You should notice something is up with your chart by day 5. It's pretty cool actually.

By day 5? Not necessarily. Implantation hasn't even occurred at that point. Plus, not all charts follow a perfect pattern.

With my first BFP, I had no idea until the day my period was supposed to show and my temp went back up a little. Up until that point, it looked like every other chart I'd ever had, complete with the drop on 12 dpo. With this BFP, I had a feeling at 9 dpo when my temp didn't dip like it usually did. It happened to mean something for me but it could just as easily not have.

You do get to recognize patterns but you also have to be careful not to get too hung up on the temps.

If you didn't know until the day you missed your period, then I think something might be up with your charts, or perhaps you chart based on only one symptom? There's some great research out there on charting and charting is the earliest possible way to confirm a pregnancy with 98% accuracy. Through charting, it can be confirmed days before a home test would catch it.

As I said, that first BFP chart looked like all my other non-pregnant charts except for the slight rise on the day that my period should have started, after it dropped like it always does the day before. It turned out to be a chemical pregnancy, which is probably why it didn't look any different. My hormone levels likely weren't very high. So, it wasn't because I don't know how to chart, but thanks for assuming that.

Believe it or not, I have read Taking Charge of Your Fertility and taken the Fertility Friend lessons. I actually do know how to chart. But nowhere in either of those resources does it say that your chart can tell you at 5 dpo that you are anything other than 5 dpo.

allgood921 · November 2013

This is my first pregnancy, but I got an immediate BFP on CD 28, or 11 DPO. And that was on a cheapo blue dye test. I'm sure I would've gotten an earlier BFP if I woulda used a FRER but I didn't want to chance dissapointment.

abrazz · November 2013

With DD I had to go to the doctor because I had a UTI that wouldn't clear up. I loved my PCP and he had given me an antibiotic that wouldn't affect a pregnancy since we were TTC. He did a pregnancy test at the second appointment and he came back and said, you are barely pregnant lol. I was 5 days from my period starting (according to charting). That was a longggg 40 weeks since I knew so early lol.

CD 19 or 8 DPO.

I got this bfp roughly 6-7 dpo but a full 8 days before expected period...and that was with midday urine. I wonder if it would have been positive a day earlier with FMU.
