Period after D&C

I had an ultrasound at 11 weeks then started cramping around 15 weeks. I was lightly spotting around 16 weeks.

We went to the hospital (Family Day Weekend) after 2 mornings of light spotting and there was no heartbeat. They flew me down by air to Toronto to have a D&C since I have a bleeding disorder.

My period has been all over the place lately and I have never had spotting in between my periods around ovulation time until last month.

Were your periods all over the place after a D&C or more normal?
