Can you?

Can you get pregnant on cycle day 8,12,13? I’m on cd 17 now and I’m sick and fatigued a lot I sleep all day and can’t sleep at night almost until daytime but I’m tired all the time and can’t sleep the smell of food makes me sick and all I’ve been eating is chili and crackers for the past week i don’t think I’m pregnant but it just hit me that when I logged sex I was apparently ovulating... oops... idk y’all will probably say I won’t know till I test but now that I know it’s a possibility it’s gonna freak me out...
