My first day of last period was 6/28/07 and light period lasted until 7/3/07... now seven months pregnant with first baby. I unfortunately was unfaithful to my boyfriend on July 2nd, 3rd &, 5th while on vacation... but he wore condoms. When I returned on July 7th, my boyfriend and I celebrated my return A LOT without any protection. And we continued to celebrate through the weekend and the following weekend. I started noticing signs of pregnancy &/or next period, i.e.. Tender swollen breats & crabbiness in the third week of July. I believed it was pre-period symptoms which I usually get a week before my period but that wasn't due until July 27th. I'm usually by the day - 29-day cycle - maybe give or take a day.

I quess I'm wondering what's the percentage chance that the beautiful baby girl I'm carrying is not my fiance's baby. I love him dearly and I'm not proud of the decision I made on vacation and want us to be a family.

Thank you

The timing is way to close to tell.

The last time you cheated was on the 5th, then you slept with your boyfriend on the 7th... with just 2 days between... the child could be eithers. Not to mention, that sperm can live in the body for up to 5 days. So while you were having sex with your boyfriend there still could have been live sperm from the other guy. (given the condoms may have failed).

The only way you will know is by doing a DNA test once the baby is born.

Its more likely you boy friends child because of the no protection thing. However like Mack said the dates tell us nothing.
