I have been with my current boyfriend for three and a half years. However, we took some time away from each other (for almost a month total) between Mid-March and Mid-April. Around the first few days of April, I had sex with another man one time (which was the only time I'd been with someone besides my current boyfriend). We used a condom; and if I remember correctly; he always used the withdrawal method.

I had my period in April (after me and the other man had sex) and again in May. Right after my period in May, my boyfriend and I had sex numerous times. Each time was to completion (he ejaculated inside me); and without any type of birth control whatsoever.

I realized in early July that I missed my period; and I took two pregnancy tests. Both were positive. I'm now beginning to experience morning sickness/swollen, tender breasts (just within the past two weeks).

My boyfriend insists on having a paternity test; since he knows I've been with one other guy one time (in early april). I'm just curious about the chances of me actually being pregnant by that other man. Especially after two periods. Any help/suggestion would be great (:
