Hi! this is the second month of taking my new pill, I changed after two and a half years of using my old pill, I had my period in the 7 day break. I started the 2nd package and on the third day I had a couple of lose stools, it wasn't really diarrhea, two hours before taking the pill. I took my pill at the normal time that day and after I had intercourse. Now I am halfway through the package, my boobs hurt and I have stomach cramps as if my period is returning, I have acne. I have not had intercourse but just that one time. Now I am interested are these side effects of the new pill or could I be pregnant? thank you!
