I feel like I’m screwing myself out of my fertility even though I know what I want

So I have PCOS and endometriosis and I am 23 years old. I got an IUD because I do not want kids right now. Like I am 110% positive that I don’t want kids right now. But do I even have the luxury of waiting? I know that I’ll more than likely have problems conceiving when I am trying to get pregnant. I know the longer I wait the harder it will be for me.

So I keep asking myself if I’m screwing myself out of my fertility and another part of me is wondering if I’m okay with that because the thought of having a baby right now.. id rather rip my hair out. But what if that changes?

Good lord, I need some outside input. This is a major source of anxiety for me.
