So my boyfriend and I had sex 2 nights before my period ALWAYS starts and he came in me (dumb on my part, I know). I am on birth control but was on my first sugar pill the night we had sex. So I took Plan B the next day (the day before my period starts). It's been 2 days since my period should have started and it's NEVER late. I've been feeling light cramping but that's it. Is it possible the Plan B messed up my hormones? I'm freaking out!!
