Hi, I had unprotected sex on June 11 and took plan b early morning the next day. I just had my period before having sex and taking plan b but got it again on June 17, after I took the Plan B. I was supposed to get my period again on July 12 but I'm a few days late and I have cramps and my breasts are tender. My periods are kinda irregular too but I'm really stressing about it and freaking out. Is this normal or am I pregnant. Someone please help ://
