Ethinyl estradiol / norethindrone
"I've been prescribed this birth control since my 6 week checkup February 14th but I didn't start taking pills until March 12th After sexual intercourse, but I wasn't taking them everyday like I should. My period still came on a couple days early and was regular but I have cramps even after my period. A couple of days ago April 8th I started taking the pills everyday and the cramping are starting to decrease but I have headaches and My stomach bubbled up like I had diarrhea & I felt nauseous at one point ."
