Has anyone conceived from BD on O day/day after O, with confirmed O?

Not sure where to post so please move if it is best suited elsewhere.

Due to my donor being away I was only able to inseminate the morning of O and the morning after. Unfortunately I messed up on O day and the semen just pooled around my opening before falling out, so I know I probably have no shot.

I was a naughty pink swayer and looked through over a 1000 FF pregnancy charts that supposely resulted from O day or O+1 BD. Only 2 of these charts had the correct O day marked IMO. 2 other charts may have been accurate but there was missing data. ALL other charts, O was clearly assigned prematurely, often by several days.

So has anyone actually gotten pregnant from this timing who is sure of O, via thorough charting or better yet ultrasound/bloodwork confirmation? I'm thinking it's basically impossible based on my 'research'.

There were a couple of studies done on timing of BD in relation to O and the percentage of pregnancies that resulted. The day of O was determined by BBT with one study and with estrogen to progesterone ratio in the other. An attempt on O day has lesser odds of pregnancy than O-1 or O-2 but still better odds than O-3. It's not a perfect study by any means and I'm unsure if couples only DTD once in the fertile window, but it may help give you an idea.
This is the chart from the study:

From what I understand it takes about 12(?) hours for sperm to capacitate so if you inseminated in the morning and didn't O until that night, there's still a good chance. Really I think any attempt in the fertile window gives you a chance but I know it's easy to feel discouraged. I hope this is the month you finally get a BFP. :)

I did with a prior pregnancy I miscarried. I had sex on the morning of O day and O'd in the evening. DH had been on a business trip so no sex for a week prior. I'm certain my dates were correct too by charting (CM, CP, BBT). I had no expectation of getting pregnant that cycle since for me I've pretty much always needed sex at O-1 to conceive.

I agree totally with your analysis and had also observed the same thing back on IG. A lot of the people who said they got "boys on O day" didn't even DTD that day or else they didn't have a temp on one of the days that cast the whole thing in doubt.

I got a bfp this month and I dtd on o night.Obviously I don't know exactly when I ovulated. But I'm guessing evening bc cramping stopped, it could be the next am as well. I didn't temp.

Cramping doesn't tell you when you Oed. It can stop before O, or carry on for days after O.

Congrats on BFP!
