All alone in the bathroom on NYE...

At my friends house and planned on having a fun night but instead I'm alone crying. I didn't know she invited her two other friends and they all have babies. All they talk about is baby stuff so I cant join in and they even hinted they wanted me to take a pic for them of just the 3 of them and their babies. My husband is luckily here and is trying to being protective but I know it will just be worse if he says something. I tried putting on a good face and being nice but Idk if I can. I just feel so alone and what is worse is this is one of my favorite holidays.
