Progesterone and clomid while breastfeeding

Well we have been ttc sense my ob gave us the go ahead 6 weeks pp and still no period or anything. My son only eats about 4 times in a 24 hour period and he is on the bottle at night. Has anyone had any luck while breastfeeding?? I don't want to ween him and I don't think he wants to yet he's 11 months. Has anyone breastfed and took progesterone to start your period and clomid for ovulation?? Thanks girls
