Need Clarity!!

[Joan7447]

Trying to eliminate possible conception date.  My LMP was May 25th 2013 the time before was April 28 2013. I am always pretty regular.  I had unprotected sex on June 1st and June 7th. And he ejaculated in me. Using online calculations estimates that time frame was my fertile window.  I had protected sex which he did not ejaculate in me, but not sure of pre *** before condom on June 17th which would be 6 days before my period would have been due(June 23rd). I missed that period and took a pregnancy test June 28th which came back positive.  Is there any chance I could have conceived 6 days before period June 17th was due June 23rd or is that too short a time between sex and when my period was due. Are the June 1st or June 7th dates obvious?

Given the regular nature of your periods, the June 1 and June 7 dates would seem to be in the right time frame and the June 17 date would seem to be too late.  Did you have any ultrasounds early in the pregnancy, and if so, did they give you an estimated due date from one of those?

Yes on July 18th US measured 7 weeks 4 days and his due date is March 1st. It has been consistent through out pregnancy and I have had 3 ultrasounds since all on same pace.  His measurements are also accurate to the week. I'm probably just nervous about pending delivery because I did use condom on the 17th with my ex when me and my current bf were on a short break and it seems a little to close to period due date of the 23rd for fertilization and implantation to occur. I would assume anything that close to shedding would not result in a viable pregnancy. I just want to eliminate the 17th date as much as possible to get some peace of mind.  I remember having ovulation like discharge on the 6th and 7th also.

If the due date given to you at 7w4d was March 1, the likeliest date for getting pregnant was the 8th, and it appears that the very latest you could have gotten pregnant was several days before the event on the 17th.  I wouldn't worry too much, but might get a DNA test with the other guy after the baby is born to put the whole question to rest.
