Sorry this might get confusing, But I'll try to be clear. I had unprotected sex a couple times with my boyfriend about two weeks ago (17th & 18th) and it was towards the end of my cycle, because I was supposed to start my period on the 27th and it's not always exactly on time. However, I did take the morning after pill around the 20th of April after I had recently had my period and the pill cause me to have it again soon after, which is what it does. But now I'm 4 days late and I have been having serious cramps. I normally do have moderate cramps, but they only last a day or two and then I get my period. I have been having these cramps and pains for nearly a week. I don't know if the morning after pill just really messed me up or if this is the beginning of ectopic pregnancy. I realize it's really early but these cramps have me concerned and I would appreciate advice.
