Need advice how to handle this.

Now, before I start the story, I am not jealous or anything. I am very happy for her, I just am sad as most people would be, but not because if the pregnancy but because I wish I also was pregnant.

My friend since Jr. High just text me and told me she might be pregnant again. She has 2 kids, this would be her 3rd and her 2nd just barley turned 5 months. She is asking for advice on things and I am trying to help her and I want help her, but I also don't want to talk about it. she knows full well how hard I'm trying with no success for over a year and said she didn't want to make me upset and that she was talking to other people about it as well. what is something I can do to help her but also get over these feelings. I've also been dealing with a girl that hates me and I hate her and we have for years rubbing her pregnancy in my face because this other frind told her I'm trying and struggling. the one rubbing it in my face literally is so petty and low she uses other people's phones and Facebook's and stuff or makes new ones to send me pics of her sonograms and belly bump. I'm just really struggling ladies.
