Could I be pregnant?

Next time don't do it with out protection.

Plan B only good for the first 72 hrs.

get a pee stick and test it out

yes you can still get pregnant during period but is rare

Likely not pregnant but there is a always a 2-5% chance on any given day that you can get pregnant regardless of where you are in your cycle (50% day of ovulation, 30% day after).

Please don't take that chance again. Use condoms and get yourself a reliable form of birth control.

It's not very likely, but just to be safe you should pick a pregnancy test at the store.

I don't think that you are pregnant because just like spartcus said when we have our periods are uterus is cleaning itself out and there is no egg to be fertilized s0o0o0 yeah if you are still concerned then you should take at home test just to be sure.

I don't think so. I know that when we have periods, are uterus is cleaning itself out, and I think the eggs are cleared out too, which would mean no baby.
