Just need to vent. I will be a good mom!

So literally everyone I know is pregnant right now or just had a baby. No one knows that my husband and I have been TTC for 9 months now. I have 2 much older sisters and nieces and nephews that are 10-15 years old. Neither set of parents have pressured us for grand babies which is nice considering we have not gotten our BFP yet. Here is my problem. Every time I tell my mom about a friend that she knows being pregnant, had a baby, or I'm getting a gift for baby shower just pretty much anything baby or kid related, my mom says "now y'all don't get any ideas yet" or "hope y'all aren't thinking about it". She has said this so many times I'm starting to get a complex over it. I finally told her today to please stop saying things like that. I told her we weren't planning kids right now (I lied) but it bothers me that she keeps saying it. I told her that it's not like I'm 15 years old that I am almost 32 years old!!! She said I forget you are getting that old. Does she think I'm going to be a bad mother? The comments have gotten under my skin. My husband and I are 31 years old, have good stable jobs, own a house, and are financially stable. I'm a Doctor for crying out loud. Sorry just had to vent and get my feelings out there and didn't know where else to do that. Thanks for listening and baby dust to all! 👶
