i have been on bc for over a year and a half and have always had heavy periods. in sept, i lost my virginity (protected sex) a few days after ending my period, and experienced minor bleeding for the following day or so. i have never spotted on the pill before, but figured it was because i had torn my hymen (could it have been implantation bleeding that soon?). my period arrived on time, but it was light. i took a hpt out of concern but it was negative. i continued on the pill and my next period came on time as well, it seemed normal but not as heavy as i used to experience it. over these past months, i have had aches in the left side of my stomach and lower back. it is not kidney related as i have been tested since i have a history of kidney infections. ive noticed my entire stomach bulge (moreso on left side though) with faint strech marks, i feel slight pains but most of the time it just feels as though smthg is there. i have symptoms such as fatigue, frequent urination, odd cravings, and headaches. am i paranoid or could i be pregnant? would a doctor have known this already because i have done a number of urine tests so far when looking for kidney issues? is it more likely to be constipation (though i havent noted a difference in my bowels) or possibly a hernia? any suggestions?
