Really tried this month

Been NTNP for 15 months now... our schedules are weird so for maybe 6-7 of them we didn’t even hit the ovulation window... but I’m getting worried. Don’t wanna go to a doctor yet especially during a pandemic but starting to think somethings wrong with me.... other people get pregnant the first month they come off the pill or something so idk what’s wrong with me. I have no health conditions, I’m healthy I eat well... 🤷🏻‍♀️ and I’m 30 so I don’t have too much time 😭 we did it on the right days this month and I already feel cramps like I normally do 7-8 days before every damn period
