My mom won't stop talking about her and others' pregnancies

I'm sure this is partially because I'm hormonal, but I'm about to lose my freakin mind. My mom was so excited for me to be pregnant (now 13wk) but every time I try to talk about my pregnancy, she interrupts me to tell me the story of her pregnancies.

Dear reader, I have been hearing these exact stories, word for word, for THIRTY YEARS. No matter how many times I say "Yeah I remember" or "You've told me this" etc etc, she just keeps going. It's just so god damn frustrating to feel like you have no one to talk to.

Also, she had babies 30 years ago. Some of the stuff she talks about wouldn't happen today. It's exhausting to listen to her talk for ** literally ** an hour with little to no response from me.
