Any suggestions?

I just had a miscarriage a month ago, I miscarried at 6 weeks exactly. Still no period yet. I'm having sex daily to try again. My OB told me to go ahead and try and that I don't need to wait. But other people and doctors have said to wait at least 3 months. Should I be having sex everyday or every other ? This is so frustrating ! Everyone says to relax and have fun with it but it was so devastating having the miscarriage, we just want to have a baby! any suggestions ?
