This might sound dumb

I’m really sorry if this sounds dumb but I live with really old people so basically was never taught this and the USA school system sex Ed sucks but how do you check for ovulation I always was curious is like a test or what I am sexually active and I’m 16 but I’ve really never asked if you know please let me know I’ve only recently started having sex with condoms/pill but it would help if I knew how to check for ovulation
