MC have sex after and end up pregnant

We just suffered a miscarriage on the 4th stopped bleeding the 8th. My husband and I both craving sex. So last night I caved no blood on either of us afterward. I’m wondering if maybe I just use protection next week since I might be ovulating again. Doctor didn’t really say we could try right away that she like to say wait a cycle based of timing purposes but him and I both don’t feel comfortable really “waiting” or using protection when we have sex. For us it’s just a bonding healing for us to have sex. And I can say after sex I definitely feel 10x better emotionally.

Did we sex to soon? Should I have waited?
