I had a miscarrage on August 17. I did not have a d&c but I did have to take Cytotec twice. My AF also came back on September 29 and I'm still currently waiting on the next. My doctor says it's pretty normal to be irregular for a while. 

I'm on my third cycle since my d&c and I still haven't had a "normal" cycle. The last two have been 31-35day cycles and very light and normally I have 28day cycles.My dr said it can take anywhere from 1-3 cycles to get normal again.

Should be normal again, but if wait a cycle or 2 before ttc again :)
