Last period 23 aug, had sex from 29 through 5 sept. on the 8 sept had another mans penis near my vagina for 20 secs, he did not or enter me, could he still of gotten me pregnant? I also took a digital pregnancy test on 21st sept with conception calculator, it said 2-3 weeks. My periods are regular and every 27 days.

And what exactly is a conception calculator? I hope its not that worthless app for your phone.

How old are you?
