Blood clots after IUD removal

Hey everyone, i’ve had my IUD since February of this year but i recently fell out last Wednesday. I started bleeding normally but not heavy on the 25th. The next day i noticed my stomach became bloated to where i look like i’m about 1-2 months pregnant. Monday i’ve had blood clots twice, once in the morning and then in the evening. I noticed it again tonight and i’m really concerned. Also, could it be possible that i’m pregnant? My IUD fell out a few days (2-3 days) after me and my boyfriend had unprotected sex but i’m bleeding like a normal period. I do have a OBGYN appointment on Monday (I’m 19 if that means anything)
