How long after a miscarriage ?

Sara
So I've been through a miscarriage last month and since my cycle is super long (56 days Normaly ... Never know with my PCOS) I am still waiting for AF ... Gyn said I should wait and not ttc the first month but I have to admit I didn't really want to hear that 🙄🙄🙄 I'm supposed to get AF next week and was wondering if anyone got through the same experience and got pregnant right away?! 
How long did it take for you to get pregnant again? 
Please send me some baby dust ☺️☺️☺️
