Conceiving After Miscarriage

I had a miscarriage that started on March 1st this year, I have been having weekly blood draws since then to watch my HCG. It’s now almost May and my HCG just got back below 1. I’ve had a cycle since the miscarriage. My question is even though my doctor recommends waiting another cycle before trying, would it be okay to try in May anyways? I know it’s best to listen to the recommendations, but we were wanting to start trying in May. But, we are going to avoid getting pregnant in June because we had a baby born in March last year.
