I have the same question. I had sex with my boyfriend 2 weeks ago but I came on my period in the middle of the night after we had sex. I have been really tired lately ,I feel like I have to vomit in the morning and I have a discharge. I was going to take a pregnancy test but I didn't want to get a false positive or a false negative. Should I wait an see if I miss my period for next month first??

You are now playing the waiting game. You need to wait to see if your next period comes. If not, remember to test using first morning urine.
