TTC first time 20 yrs

Hi guys! I’m TTC for the first time and I was directed to this app. I have a feeling I might not be able to have kids (IDK why) and I’m trying to remain positive... I’ve never had a scare or anything but I was on birth control for years while having unprotected. I’ve had my IUD out for 8 months and it’s go time. There’s a 24 year age difference between me and SO... I think I’m doing everything right but omg this is stressful already 🤦🏽‍♀️
