Conception vs Implantation

[Unsureone1987]

Hey peeps! Kinda confused on who is the father of my child. Ok rewind to June 2013. I had sex with guy one on June 26, 2013. My last period was around the 14-19 of June. I know for a fact it was on June 18th because I went to ER and they needed urine sample and it was bloody and I had to shamefully say I was on my cycle. Anywho back to the sex situations ok, I had sex on June 26, 2013 which is my conception date. I had sex a week later with guy number 2 on July 3, 2014 which is the implantation date. Guy number 1 lines up perfectly with my due date and birth of child but baby looks like guy number 2. Can anyone help me, can you get pregnant on the implantation date, am I just being paranoid BC I cheated.

The calculator I use gives June 27 as the estimated conception date, and if it was in your 8th week it would only be one or two days off either way (there is a very small margin for error when using ultrasounds to try to determine a conception date if they are in your 8th week).  I would say the guy with whom you had sex on June 26 is by far the most likely candidate for dad.  You could do a DNA test if this is going to bother you forever.

At 8 weeks I got that due date from ultrasound

[AnnieBrooke]

And was that from an ultrasound?  If so, how early in the pregnancy did they give you that due date?

Yes, my estimated due date was March 19, 2014.

The "my conception date" and "my implantation date" stuff only works if your cycles (day 1 of period to day 1 of next period) are absolutely like clockwork at 28 days or some other known number of days (like "every 30th day I always get my period" or something).  If your cycles vary in length, you can't be certain a given day was your conception date or your implantation date.  Did you have any early ultrasounds (like, 6th or 7th week) where they told you an estimate due date?  If not, you should probably do a DNA test.

Oh and FYI I used a rubber with guy #2 but of course there is a but. It was stuck in me.
