I had unprotected sex around 11/11:30 and I took the pill between 12 and 1 can't remember exactly when but I knew I took it like 25-30 minutes after . It happened on august 15 and my period had just ended on the 11/12th . I took the pill and still worried . The next morning I had a headache and got them here and there. After that I began to have a little stomach pain with diarrhea. It's august 24 and I'm still having some stomach pain and frequently using the bathroom (#2) but when I used the bathroom I saw some pinkness when I wiped. My period isn't supposed to come on until September 6 . Is that normal? I'm freaking out
