Troubles :(

Why am i having so much trouble getting pregnant?? I’m 25 years old, pretty healthy and in a stable relationship. My cycles are some what normal besides lasting pretty long. Last cycle was 53 days. This year I’ve been averaging 36 day cycles. I was on the birth control pill since high school, did a couple of years on depo. Been off the pill since July 2022. Been constantly actively trying since January of this year. Just very confused on how ladies around me are getting pregnant so easily but I’m struggling. Thanks in advance for the thoughts!
