I had unprotected sex, using the pull-out method about four days before ovulation and am currently two days late on my period. I've been experiencing my regular period like symptoms (cramps, bloating, tender breasts, etc.) as well as a burning sensation and tightness in my uterus, some slight lower back pain and frequent tiredness. I am on the pill but I heard that if you do not take it at the same time everyday it may not be as effective. I take it whenever it pops into my mind which is usually between 10pm-1am everyday. I was wondering if I could possibly be pregnant. I'd like to know if there is a possibility before I take a test.
