Does anyone else get tired of hearing from their family's input on TTC?

I've wanted to be a mom for forever, and I have 3 sisters who had their first kid by the time they were 21... I know it isn't a competition, it's just that I'm going to be 33 this year and I'm getting worried that it won't happen. My DH and I have been trying for over 2 years and it's really starting to mess with my emotions.

What's really bothering me lately is the input from our family. I have sisters saying "it'll happen" and a MIL who complains that she "needs more grandkids". On top of that, there's my own mother making comments like "you're going to get pregnant with twins this month, god told me", and "you don't even realize you're pregnant yet do you?".

It's like I can't even allow my mind to think I could be.. The hope hurts too much. AF showed up again today.

Has anyone dealt with this? Your whole family waiting on you to join the Mom Club? Is there any way to get them off my back?
