Clomid and ttc

Been ttc for about 15 months now. Dr just prescribed 6 months of Clomid and estrogen. I can't start either until next month. Just looking for success stories. Also have a couple questions. When should we ramp up the BD on the Clomid, how often should we BD, with a retroverted uterus should I lay on my back or belly and for how long? These are all things I forgot to ask her lol! We've been BDevery other day CD 8-16ish, belly laying for at least 10 minutes. We already have a child so idk why it's been much harder this time!!!
