2nd period - is this normal? HELP

I had my d&c about 12 weeks ago. My first period was weird. I had spotting / discharge to start, then a period for a few days. It stopped and then I had a few more days of bleeding.

My period was technically late for my 2nd period and I was starting to worry that I was pregnant again. I was thinking that it was late because of the strangeness of my 1st period.

I haven't been off the BC pill in about 19 years and was only off for about 2 months before I became pregnant. Prior to going on the pill my period was all over the place.

Anyway, my period has been very heavy. Before going off the pill, my periods were getting lighter and lighter (I'm 38 yrs old). I leaked for the first time in I don't know how long (partially because of the way I was sitting perhaps so the pad was not in the right place. BUT I've also had a lot of large clots.

not sure what to think?? Is this normal?
