Hi,
Me and my girlfriend had unprotected sex once on 3 months ago on 22,May but I ejaculated outside. Before a month she got her period around 25,April and after sex she got her period on 27,may .Then from next month she stopped period I asked her for home pregnancy test but she rejected because she told me that sometime already she had irregular period. Later I forced her, then yesterday she told me that test was positive.I am wondered that how she can be pregnant because a woman is most fertile on 14th day of period and she got her next period after sex till now we had not sex.Even I heard that home pregnancy test does not give for sure report
Help me out what should I do. I do not want this child .I am afraid kindly help me.

You will have to wait until this baby is born and then have a DNA test to determine whether it is yours.
