Feeling bad.

My cousin just announced over fb that she is 11 weeks pregnant. I feel horrible because I want to be happy for her. But I am not. This will be her third and I am wanting another one so bad. We tried for 1 month then he changed his mind. Last night he actually said he's as indecisive about that as I am pretty much everything. My time line for having one last baby is very small because of health reasons. I am feeling jealous of her having another baby and beginning to feel resentful towards my so. :(
