Well-meaning friends & family

Earlier this year my husband and I went through fertility testing to see what might be the problem. We have no glaring issues aside from age (I'm 38), but have still not gotten pregnant after 2 1/2 years of trying. I'm frustrated and I feel broken. I'm uncomfortable discussing TTC with most people in my life, including best friend and mom. I know everyone means well, but inevitably I get the unsolicited advice or questions like "have you tried [insert whatever advice you've heard here]?" Or the "well you just need to have more sex lol!!" Personally I hate that. I don't want other people to dig into this very personal and private part of my life. does anyone else feel this way?
