Long cycles since miscarriage

Jess
Does anyone else have really long cycles since MC? Mine are around 37 days but I only have an 11 day luteal phase which I know is too short. Really starting to worry about it. Wondering whether I should just go to my GP and ask about it.
I'm cd20 now and still no ov, last month it was cd25/26. I know I shouldn't stress about it but I'm worried that the MC has ruined my chances of getting pg.
What do you think?
