Girls I need your advice!

So She was just trying to be nice.. finally told her last week we have been ttc for 9 months.

Ps My sister got pregnant on their first try which wasn't even a try.. love her and she's my best friend and so understanding but my mom is so opinionated!

Mom had asked every time Wesee her, hinting about nurseries, so finally I just said yes we've been trying for 9 months! She doesn't get that people keep this to themselves. She apologized via text and this week she set up a call to inform me that she's done internet research on what the best times to do it is 😣 and proceeds to tell me not to get negative always stay positive....and that oh yeah now that she thinks about it she has a friend that tried for 2 years and another for 6! So it'll happen I should just be patient! Thanks mom... anyone else have an opinionated mom like this? I'm left feeling worse and I was already struggling with this and now feel diminished. But sometimes I know I can get sensitive. Should I have said something like "hey mom, couples tend to keep this to themselves until hey have good news so that they don't get unwanted attention or questions making them more stressed"
