Hi there, I'm an 18 y/o female and I have taken birth control ( Kariva -- to be specific) since I was 15 to treat PCOS. About a month ago, I had intercourse and afterwards I bled heavily and had cramps for a week. I should not have gotten my period for another two weeks according to my pills. When I took the pills that started my period, It was very light and ended two days early. We used a condom but I'm scared. I've been constipated, had thicker vaginal discharge, and pain in the left and right sides of my abdomen. Why did I bleed? Why am I having weird symptoms now? Could I be pregnant? Am I just freaking myself out? If any one could answer these questions it would be greatly appreciated! Thank you!
