I found out early this week that I had a miscarriage - I was 6 weeks pregnant following a fresh cycle of IVF. I'm still waiting for my period to start (stopped meds on Monday of this week), but the MD told me that we can go on to do a frozen cycle immediately. I know you posted this question back in July and am curious to find out if you went through with the frozen cycle and if it worked.
I have recently had a mc at 11.5 weeks after a fresh ivf cycle and they've told me to wait 2 cycles before a FET. It really depends on when you miscarried as if it was earlier, then you probably wouldn't have to wait so long .. after a certain time, you stop being an ivf patient have the same protocol as any pregnant woman so this is what mine is based on .. I hope this helps .. good luck!!
