I have cramps could It either be pregnancy or the end of ovulation

Me and my boyfriend had sex 2 days before I started to ovulate then on 2 of my ovulation days. I'm on my last day of ovulation. We've been trying for 3 months. I have cramping just mild ones, I really wanted chicken wings lol so I got some ate 2 then didn't want anymore. Could this be early pregnancy signs ?
