I don’t want to sound silly by asking this question; but can you get pregnant if you’re not ovulating?

Although I’m not stressed or anything I’m still curious because my boyfriend came inside of me 2 days and I’m not ovulating. Could this result in a baby???

Also; over the past 2 weeks or so I’ve been peeing a lot more and the urge to pee is pretty strong even if it’s a little bit. I had a dizzy spell and was really nauseous the other day. I’m also really tired. Should I be concerned?? Or is this maybe cause my period is due in about a week? Please let me know☺️☺️❤️
