trying to get pregnant!!!

Destiny
So me and my bf are trying to get pregnant and we have been trying for a while now and i still am not pregnant yet. Does anyone have any suggestions on helping me find a way to get pregnant???? I am trying so hard doing everything possible and its not working. I feel like i am failing him. He has gotten his ex pregnant before but it was a still born and he wants this just as much if not more. 😔😔😔
