Are we all scared we're secretly infertile until we try to conceive?

My husband and I decided to start trying in a few months and it hasn't left my mind. I know I'm a highly anxious person, but I can't stop obsessing over if my periods are normal and if I'll be able to get pregnant when we try... telling myself this is probably common and I'm not actually just getting the right gut feeling 🫠

Since I started all this stressing, my cycles went from like ~32 days to now ~40-42 for the past few. My OBGYN says not to worry yet and it's probably stress, but I need things to go back to normal so I can stop worrying so much!!!
