pregnancy: I want a baby

Destiny
It's been so hard on me I lost 2 babies both miscarriages n I want a baby but I'm starting to think something is wrong with my insides...Any conclusions or thoughts as to what's going on? 
Before it took me. A while he would ejaculate in me and I still wouldn't get Prego. Why is that ? 
I just need some tips on how to get pregnant effectively
