hi kayandjay, welcome to bellybelly. I hope you find all the help and support you need here. I know i did. I joined after my missed miscarriage (same as yours) in 2007, just wanted to let you know that i know of people who didnt wait at all and started trying straightaway,some with luck too!
also after my mc AF was all over the place, in regards to cycle length anyway, 21-38 days, used to be spot on 28.
anyway, have you checked out the ttc after mc threads? the girls in there are all going through the same thing, waiting, testing etc. you may find some more support and even make some friends.
Good luck, I hope you get your BFP soon. xx
