My husband thinks he knows it all

My husband swear up and down he know a woman body better than me because his mom had 10 kids. He says a woman don't have to ovulate to get pregnant and a woman ovulate up to five times a month smh. He really got upset and told me because i'm 35 with one kid I'm wrong lol he left and everything. Smh I'm so tired of his b.s. over dumb shit. He's saying without ovulation period lol not early ovulation. We know you can still get pregnant if don't have sex during ovulation but you still have to ovulate to get pregnant. I hear sperm can last up to 4 days or something like that
