I was recently prescribed Loestrin 24. I started taking it the first day of my period like my doctor told me, but i also had unprotected sex everyday until now (I have 5 pills left in the pack). During the whole month i missed acouple because i wasnt used to taking the pills yet. Then i noticed my breasts have been extremely sore but i ignored it thinking it was from the pill. 3 days ago I also noticed blue veins all over my breasts. I still have about a week until my period (if it comes). Could i be pregnant?
