For a month and a half I was on the birth control LoSeasonique, on June 6th I switched to LoEstrin, but when I switched birth controls I didn't stop the LoSeasonique and have a period, then start the LoEstrin, I just immediately started the LoEstrin. I had previously been on LoEstrin and while on it before I had no problems with it, no spotting, cramping and extremely light periods.
On June 10th I had unprotected sex. Within the next few weeks, especially last week, I began to feel extremely nauseous during the day, I was tired, moody, I was having mild cramps/back (almost on my side) aches, and was constantly urinating, and then around June 23rd I began having a dark brown/red bleeding. It was lighter than a period, but heavier than spotting (it was constant) and then I noticed that there were a few large clots/clumps.
I just reached the end of my LoEstrin pill packet today, so will start a pill-period, but I have been bleeding for a week now (but it is getting lighter/less painful). I took a pregnancy test just to be sure, which came back negative, but is it possible that I had a miscarriage that early on and at only 19?
