If you had sex with an condom on and your period became a month late .. your mate says he had a condom on and that he went in the condom. hows that ?

What?: If you period came late, but it did in fact come, it's pretty darn unlikely that you are pregnant. If it in fact has not come yet, then do a pregnancy test. If you can't trust your partner to actually put on a condom when he says he is, then i would suggest that your relationship needs a little work.

Not 100%: Condoms can break, leak or not be put on properly. You should get a pregnancy test.
