Baby shower question

November ladies, wondering when your baby shower is and if it is all planned. My MIL had said she wanted to throw mine at the end of September/beginning of October but we really haven't discussed it any further and I feel like invitations should be going out by now if that was going to be the timeframe. She hasn't asked for a list of names or anything. It's not a big deal if I don't have a shower but I do have some friends asking about it and how they can help, etc. I feel pushy bringing it up though. Opinions out there on if I should just let it go or how to gently say when/how do we plan on getting this together? Also wondering your dates since we are all due in November...
