wanting to get pregnant again

How long did you wait after a miscarriage to get pregnant again? Did you wait a couple of months or within the first month? I went to 2 different doctors, one told me to wait 2-3 months and the other told me I could start trying within the first month I'm so confused..... my miscarriage was at 7 1/2 weeks natural no pills or d&c.. stopped bleeding this past week on Thursday and we had unprotected sex last night
