My last period was 25 days ago, I had unprotected sex a few times in 1 night and it was 2 days after I got off my period, (23 days ago), I was supposed to start my period today, I did take a test yesterday, took over 5mins to show a answer, it was digital pregnancy test the other day, was negative, should I take a different test? it took over 5mins when the box said 2mins. I've been peeing a lot, eating a little more, craving things, feeling very nauseous and throwing up a little. Should I test again??
