Afraid of disappointing my boyfriend

I’m so afraid I’m not going to be able to get pregnant. I’m 34 years old and have never tried. My partner has 2 kids, with 2 different women and they both got pregnant within 2 months of trying. It’s been 4 weeks for us and after getting off of birth control I haven’t even started a real period yet( just a withdrawal bleed) so I’m getting doubts that this could actually happen for me.

I know it’s not a contest or a race. In my mind I know that. But it’s also something I’ve been waiting for my whole life, I’ve always wanted to be a mom. And I feel like maybe I waited to long and it just won’t happen for me. My boyfriend really wants this as well and I’m afraid that if I don’t get pregnant within the same time frame he’ll be disappointed as well.

The nerves are so crazy and it’s all I can think about.
