Ttc after miscarriage

Evelyn • wife since 2017 and mom of a beautiful two year old boy and baby girl on the way! Both my rainbow babies 🌈

Girls I have some questions!! So I just had an early misscarriage last week, it was reaally early they said I probably was just a few days pregnant and the baby just came as a regular period, now I want to ttc this next months but. The doctor told me to wait at least one cycle so the dates of my next pregnancy will be more accurate, but since my periods are super irregular isn’t that a problem too? They wouldn’t still be able to get my due date from my last period.. also is there any problems if I start ttc this month? Help please!!
