My period came 3 weeks after my mc. We were told to wait one cycle so we sat that one out and then conceived DD the first month we tried after getting the green light from my doctor. From so.e women it can take longer for a period to arrive. I think up to 8 weeks.
It returned about a month almost to the day of the miscarriage. It was May 28th and AF returned June 22nd. I was only about 6 weeks so give or take depending how far you were. Sorry for your loss momma
