FET today!! How long before ‘I know’?

Sa

Today is my first FET. I’m so excited! I’m doing FET the first cycle (natural) after retrieval. I didn’t eat any special diets, just carried on life normally as I didn’t want to get stressed out.

My and my hubby are formally tying the knot in a ceremony with family (we are already legally married) in April and it would be my dream to be able to announce we are expecting on the day. I am 37 and we’ve been trying for a while.

How long after FET do you need to wait before you know for certain you are pregnant? Anyone else had success with natural FET?
