Still trying 😔

Me and my fiancé have been together going on 4 years now I'm only 22 years old, we have been trying to get pregnant ever since we first met. I seen many different GYN doctors got ultrasounds blood work and I don't have PCOS or and infertility, I do suffer from Cyst on my ovaries but he said its normal due to my sometimes irregular period. My period comes faithfully every month now , and I try every night to have a baby and still nothing 😔 has anyone been having this problem as well ? Also on June 18 my fiancé has a appointment with his doctor and his gonna tell the doctor to give him a sperm check test to make sure it's not him whose infertile.Â
