Miscarriage? A true mystery!

I hope someone can help me out. I had my period on February 5. It lasted 7 days and we had sex on the 12th. I thought we were safely away from ovulation day- but turns out I somehow conceived because I got a faint positive pregnancy test (see photo) on Feb28. This means I got pregnant somehow 7 days before ovulation occurred on the 19th??? I must have ovulated early - however since my test didn’t turn positive until the 28th... it must have implanted very late? Can sperm live for 7 days and then can an embryo take 8 more days after conception to implant? Seems unlikely.

I called and had my hcg level checked and on March 2 (4w6d) it was only 171. Which I know is way too low. Since I have such crazy miscarriage history I figured they would drop but two days later at 5w1d they had tripled to 510. At that point they booked me for an ultrasound at 6 weeks which is in two days from today.

I have virtually no pregnancy symptoms, which is highly unusual as with my viable pregnancies I was actively throwing up by 5.5 weeks. I just can’t understand how this could possibly be a viable pregnancy with my dates and levels the way they are. I am 10000% certain that we only had sex on the 12th and cannot be wrong on my dates. Can anyone unravel this mystery ????? I assume I have a blighted ovum or missed miscarriage but thought I’d put it out there In case anyone else experienced this and by some miracle carried to term? Thanks for reading !!!!

Very strange. I've read on some sites that sperm can live up to 7 days but i have never believed it. Still dont honestly. Are you absolutely certain on O day? Do you temp or take progesterone tests after positive O test?
And 8 days for implantation is normal.

If you ovulated early then this is totally possible. Early ovulation and then implantation is usually 6-12 days after conception. Even if you ovulated a few days after intercourse you could’ve still conceived.

Thank you both for taking time to read and respond. This wait has almost killed me! I still have zero pregnancy symptoms . I should be 6w2d tomorrow and go in for an ultrasound at 8 am. I am not expecting there to be a baby in there. I was not tracking ovulation or trying to conceive so I’m really at a loss at to HOW and WHEN this happened! Again ainappreciate your feedback! I’ll update tomorrow!

Believe me, crazy things happen in the ttc world. Things that people dont think possible. Babies that in all reality shouldnt be, but are!!! Your numbers were normal the first draw
I've seen lower numbers turn out to be successful pregnancies.

Just got back from ultrasound and gestational sac measured 5w3d. Fetal pole and yolk sac also there. I just can’t make sense of these dates. I go back for another ultrasound in 10 days. If there is a heartbeat and viable baby in there someone can knock me over with a feather. I’m still hesitant to believe this is viable - I should be 6w2 days today so I just don’t know! Thanks to everyone who has corresponded it helps so much.

Our LMPs are almost the same, and i'm calculating to be currently 5w4d based on i think your measurement might be right. Congratulations!!!!!

Oh my gosh are you serious? I just can’t even believe I ovulated on the 19th and somehow conceived from intercourse on the 12th. How how????? I am still weirdly symtpom free which is very abnormal so I still lean towards this not being viable. But I also have had 13 miscarriages so I tend to err on the side of caution! Thank you so much for commenting!

It seems wild but it's definitely possible!!! I'm going in tomorrow for my first ultrasound. I will be exactly 6w1d from lmp which was on 2/3/19. I ovulated on cycle day 18 and we only had sex the two days before O. So I know they can live in there but in your case I guess they are super survivors! Congratulations!!

Good luck tomorrow! How are you feeling? Has morning sickness set in yet? I’m usually so so sick by now but I’m feeling totally great except a little bit tired . I go in again the 25th for another ultrasound and am trying to be prepared for news either way. It’s hard to feel like this is progressing when I’m not sick!
