First baby was a peace of cake but 2nd is taking for ever to be concieved

Me and hubby have been trying almost 1 yr and a half and we haven't conceived our second child yet. after a year of trying I went to my GYN and discovered that I had polyps on the lining of my uterus had them removed March 2015. Started baby dance again in May and until June I had my first AF after procedure nothing as of yet. Started taking Geritol  this month already on five days I'm hoping baby number two will be conceived in August that's when my daughter was conceived five years ago.
