Pregnancy Paternity

My last period was April 26th. I was due for my period around May 24th. I had unprotected sex on May 29th. I was still late on my period and took a pregnancy test on May 30th - test came back negative. I ended up getting what I believed to be my period the next day on May 31st. I found out I was pregnant on July 14th. I expected my next period to be at the end of June and never got it. I had a one night stand on May 29th and I had sex with someone I was actually seeing all through the beginning of June and into July. I'm wondering if there is any possibility I got pregnant on May 29th?

Was the period on May 31st a normal one in terms of length and flow, nothing odd about it besides it being a little late?  If so, you don't seem to have gotten pregnant on May 29th.  Have you had any ultrasounds yet?  Did you get a due date based on the ultrasound data if so?

From what I remember it was normal. I believe I would have noticed if it was not normal.. but I'm not positive. I also started dieting late April early May and believe this may be why my period was thrown off. Usually my cycle is consistent (28-30 days). My first ultrasound is this Friday.. mostly I'm wondering if it's even possible to ovulate a week after your period is late.. I thought about the possibility of implantation bleeding - but even then, would I have bled only 2 or 3 days after sex on the 29th?

Women do sometimes bleed early in pregnancy, but not from implantation.  "Implantation bleeding" is largely a myth, women trying to get pregnant often tell each other excitedly that they might have had it, but it always winds up being their period.  I've only seen about three reports that sound like women really had it.  An embryo is no bigger than the dot on the i in this sentence at the point of implanting, if it is even that big, and the endometrium is ready to accept the egg, and almost never bleeds at all when the embryo burrows in.  You would not see days of bleeding that could be confused with a period.  If it were to happen, it might be one ghost of red one day in your pantiliner, and that would be it.

Anyway, when you get your ultrasound, tell them your last period was irregular.  Ask them to tell you an estimated due date based only on the embryo's measurements and developmental markers, not based on when your last period was.  Be sure they understand that your last period was a bit wonky and you don't want it to affect the assessment of when you are due.  They'll give you a due date, then you can take that home and either count back manually 266 days on a calendar, or use an online conception calculator, and it should give you an estimated conception day.  Also keep in mind that "weeks pregnant" are counted by the doc as beginning on the first day of your last period, so don't let that throw you.  Work from the estimated due date instead.

Hi Annie! I just got back from my first ultrasound and they gave me a due date of March 8th and also from the size of the baby they guessed me at 9 weeks. The doctor said my period on May 31st was legit from seeing the size of the baby. I just wanted to ask you again if you think it's possible I got pregnant on May 29th?
Sounds like you got pregnant in mid-June, no earlier than the 10th, probably closer to the 15th.
