Upset

So last night me and my boyfriend got in an argument about having a kid. We just bought our own house and he told me last night he wants one and we move in a little over a month and we have been having unprotected sex for over two years and still not pregnant. It upset me bc I could be infertile but then again it’s harder for some people. It just upset me a lot by the way we argued about it and I tried explaining to him it takes time for certain people. I’m calling my obgyn today but any tips? Is it my diet? Or what.
