Trouble conceiving

sade
Im 28 and my SO is 30... He has an 11 yr old and I a 10 yr old. We have been ttc for a year and nothing. I went to the docs.. Test were ran and everything came back good. He even cleared a cyst just to be sure. My SO sperm count is good as well.. I used ovulation kits, apps, different methods, supplements.. What is wrong with me? Could I be infertile! Meanwhile everyone around me is getting knocked up 😢
