I just got off my period not even a week ago, and it was my full period, not just spotting.

However, my boyfriend and I had sex during my fertile week and he didn't pull out all the way.

As I said, I had my full period. But I've feeling kind of nauseous towards the end of my period and off and on since. I didn't have the money for the morning after pill sadly. Should I wait for a few more days and see if I get any other symptoms? Or should take a test now?
