Pregnant Friends

I'm TTC and I have this friend who is due in February with her second. I usually hamg out with her quite a bit because she is a part of a larger group of friends I hang out with. Lately, It seems like all she does is talk about her pregnancy. She will even change the subject when our group is talking about something and say things like "6 days until we find out the gender" even if we weren't done talking. She gives every tiny detail about her pregnancy and constantly complains about it as well. My problem is that I don't know if she is being ridiculous about it or if I'm just upset that I haven't been able to conceive yet.

I'm having a hard time being around her right now, but if I stop hanging out with her, I have to stop hanging out with the group.

I don't know what to do...

Am I a horrible person that I don't want to hear about her pregnancy or even be around her right now?

What should I do? Does anyone else feel this way around their pregnant friends?
