I had unprotected sex almost everyday last week. He pre ejaculated in me 1 time & then went for round 2 & pre ejaculated in me again. I haven't came on my period yet like I should have.. Could I be pregnant?

You were certainly trying to get pregnant. But you have a wait a while longer before you will know. Its too early for an HPT yet.

Hopefully you will be, I know you must want to very badly. It is not possible to know at this point. You will have to wait and see if you miss your period or not. If it is late, wait till it is about one week past to do a home pregnancy test. Again, good luck
