Good afternoon. My doctor put me on lo loestriin fe to regulate and shorten my periods. She told me to begin taking them on the Sunday after I began my period. I did, but I had unprotected sex that Wednesday and Friday. That was a month and a half ago and I have been sleepy more than usual, cramping occasionally, my breasts are extremely sore and appear more full, I have had breakthrough bleeding, and my eating habits have changed. My doctor told me to allow three months for my body to get used to the pills and though these may be side effects from the pills, I can't help but to be paranoid and wonder if I may be pregnant. What do you all think?
