So last month I had unprotected sex. I got plan b about two days after. This month, I'm about 5 days late, I have bad cramps, and usually when I get cramps I start my period an hour or two after the big cramps hit. It's been a good 3 days of cramps though. Today I've had the worst cramps and I was very sure I would start because of them but there's nothing. Does anyone think I took the plan b to late? Should I wait a couple of more days before taking a test? Any suggestions? Reason for me asking if I should wait is because I had gotten pregnant before, about 3 years ago, long story short, all of my tests came out negative till I was just about 2 months.
