Concerned and anxious

Four weeks ago I had a miscarriage at 8weeks, it was my first pregnancy for both me and my husband. We just had been married for 5 months and this was a surprise pregnancy. When we lost our baby we were devastated, we want to try again but I hadn't started my period yet and dk what i should do. We have been having sex since our OB said we could once i was done bleeding from my miscarriage which I stopped the next two days afterwards. Can anyone help me know when i should start having my period my husband and I are anxious to start a family
