Fertility

Hi, I am reaching out because I am seeking at home ways or "tells" per say to know if I'm actually fertile. I have had a lot of surgeries and have been told that my chance of having kids/being fertile is very low. My doctor offered to do a fertility test, but it's going to cost me $500 out of pocket and I can't afford that right now.

Not looking to get pregnant anytime soon, genuinely just want to know before deciding to do so.
