In about 36 hours...

In about 46 hours i go in for a hysteroscopy and ablation procedure. I am scared to death that they will find something so bad and tell me i can’t have anymore children. If that’s what they say i have a huge decision to make. Do i make my fiancé choose between me or having his own children one day. No we can’t adopt because i have an ugly past from right after i turned 18, and having someone else carry a child for us is an option that is out of reach because it costs way too much for us. I am possibly coming to a crossroad and do know which way to turn... i have two beautiful girls who were adopted when i slipped into a deep depression when my dad passed, he has no children, how could i ask him to give up being a father for me??
