Friendship Help!

Last night I cried really hard. Since I've been pregnant my friends don't invite me to do anything. They assume I don't wanna do anything because I'm pregnant. My friends don't have children and don't really know or understand what I'm going threw. It hurts to know that they are making excuses for me and just flat out not inviting me to do anything. I'm just trying to enjoy my free time while I can before Ava gets here. I know I'll be too wrapped up in her to really do much at least for a few months. I told my best friend I broke down and cried last night and she just told me "don't start with that shit". She has been extremely depressed and I have done what ever I can as a friend to be sensitive to her emotions and the moment I'm feeling sad she says that to me. My feelings are really hurt I don't really know how to handle them right now. I just wish I had more moms to hangout with. Is anyone else feeling this way? What should I do?
