Period after mc

Madison • Expecting our rainbow. 💜
I had an early mc beginning of December. I just got my first period Saturday. Started with bad cramping, I mean so bad- then the bleeding started. Not super heavy though. Then the next day cramps, but extremely heavy period (heavier then my mc) also a few clots. Then the third day, it mellowed out- didn't even really bleed at night.. Thought maybe I had a short period. Then today 4th day.. Cramping again (not too bad) & heavy blood with a few clots again. I had no idea what to expect for a first period, nor do I know if there is a "normal". Should I be worried? It was odd that the bleeding stopped almost then started again. I've read places the first period can be very bad. Also wondering if my body is still expelling stuff from my mc? Any insight would be appreciated. I've never had one before. I was 5 weeks so I just had a natural one.
