My boyfriend wants kids, I don't really because of my mental health. I have concerns about the type of parent I'd be and some PTSD issues.

I also have PCOS and I read somewhere that if you don't have a kid by 30 you risk have complications and serious issues. Possibly even fertility issues. Which are still a serious question for me even before 30 because of the medical issues I have on top of PCOS. I keep telling him we need to get serious about this kid thing or he'll miss the chance to have a baby. He keeps brushing me off like he's not really interested in a kid. I am beyond frustrated with trying to tell him and get him to understand what I'm saying. I need help. It's like he lacks the ability to understand anything I'm saying or to even take me seriously at this point.
