So I missed two of my birthcontol pills in a row and had unprotected sex two days after I missed those two pills. He didn't pull out. I missed the pills on Tuesday and Wednesday of last week and had sex on Friday and Saturday. What are the chances I could get pregnant from that? I know it's to soon to tell if I'm pregnant but I've been having a lot of the symptoms and I don't get my period for another two weeks. My breasts hurt, constant headache, lower abdominal cramps, always tired and extremely nauseous all the time.
