Cycle buddies?! AF due 3/26 need up lifters

My names katie. Me and my fiancée have been TTC for over 3 years now. I need some support and up lifters. This has me getting very depressed. My sister just found out she is pregnant after she just had her second abortion a few months ago. I just don't understand why people that don't take care of there kids or people that have abortions are able to get pregnant but I'm not. I got pregnant 4 years ago but had a miscarriage. It has been one of the hardest things to deal with. I need lots of prayers and people to talk to.
