Ovulation???

Is it possible I’m not actually ovulating even if I get a positive test every moth? I’ve been TTC for over a year now. Have a doctors appointment soon but was just curious. Every time I get a positive ovulations it’s exactly 12 day until my period. I have longer cycles like 30-32 days. Is it possible to get pregnant if you ovulate 12 days before your period? I thought you needed a full 2 weeks?
