Had unprotected sex twice using the pull out method during my fertile days, so 50 hours later I took Plan b, I think it was during ovulation because I saw a lot of fertile mucus. a couple days later I had a lot of white discharge and now my period is due and I have had on and off cramping the last 3-5days and my period doesn't come. Could it be Plan b side effects? Every time I cramp it really feels like my period is coming but it doesn't, I also get pain in my ovaries, I have been sleeping more, I pee more often, I'm irritable, emotional and I have lower back aches
