Fertility

It's been more than 2 years now I'm trying to get pregnant. I had small cyst but last year on August I took it out and still trying to conceive. IUI program,Took clomid and have doctor appointment 12 days from first period but ultrasound result was the egg that my doctor expected was small ( maybe I passed my ovulation already or not yet but I think I passed it) so I took clomid again and had sex a lot (without IUI) but not pregnant. Than I'm tired of it and very sad. But I keep checking my ovulation with the stick..actually my ovulation always early not exactly 12 or 14 days from first period and not even same date that glow told me. Anybody wanna share their experience about early ovulation with me ? I want to know what other ladies ovulation, it's come early or exact 12/14days from first period or maybe come late or maybe exactly like on glow date? Please share your story with me, thank you❤️
