what did the pregnancy test say? if it was negative then probley not because it would show by now
If you got what you thought was your period, took a pregnancy test and it was negative. You are fine. You are not pregnant.
If you had sex 2 months ago,and have tested negative then very unlikely,normally you can test for pregnancy 2 weeks after the said act.its only 2 days late,wait few more days,but most likely not.
