Me and my boyfriend had unprotected sex last Monday 1/19/09,and he came in me twice in one night,but it was like a hour apart each time that he came in me,and at the beinning of this week (tuesday) I been fellin like a light cramp in my stomach,and a light back ache.and sometimes when I lean ova I feel like a little cramp what do you think this mean.

When is your period due to start? Of course there is a chance that you're pregnant since you had unprotected sex. But you won't know for sure until you miss your period.

I have irregluar periods they are kind of tricky so I really want no when to expect it.

Then you've got even longer to wait to find out if you're pregnant. If you're anxious about the timing, wait two weeks after the last time you had unprotected sex. Take a home pregnancy test with your first morning urine.

And from now on, I would strongly suggest having protected sex.
