Okay;

I started birth control the 30th of November, this was my first time on birth control ever. I’m still on my first pack of pills (Reclipsen) and I’m currently on the last active week before my inactive pills. The Planned Parenthood docter had me start the pack even though i hadn't had my period yet. So you could say I skipped a month because of my BC. Well I spotted a bit during the month (which I heard was normal during the first 3 months on BC) but on the 16th of this month (December) I started to get cramps and noticed brownish blood which I normally would get at the end of my period. So I took this as I was starting my period. The next day my cramping got worse and around midnight that night I went to take my tampon out and noticed a pretty decent size clump of blood and a clearish/pinky tissue. I put this into a clean container and washed it off and it turned out to be a dark pink tissue around a inch long/wide and a few mm thick. The clearish pink bit was a good 2 inches long ad a cm thick, like a chunk of flesh. Well this morning I passed another piece of tissue this time dark pink but a little clearer on one side this was maybe 3 in long by 1in wide and a cm thick, this was also a chunk of flesh. My mom looked at it and said it was just the lining of my uterus. I’ve read things on the internet and they all pretty much say the same thing. But I just want a professional opinion.

Also: I am sexually active, but he's never came inside me, he always pulls out a good 30 seconds before he cums. I also had a pregnancy test when I first got my pills and it was negative.
