How do I know if I'm ovulating??



My name is Camille and my DH and I are trying for our first. Well we aren't like proactively trying yet but we haven't been using protection either and I have been taking prenatal just cause they help regulate my cycles. But we are mostly just going with how we feel, but I was just curious how exactly do I know if I'm ovulating? Will there always be like a cramping sensation and is it common to feel it in the middle of my abdomen instead of on my side? Also during sex is it normal to feel more sensitive and open if I'm ovulating?Just was pretty sensitive (and amazing as always :) ) a few days ago. Looking forward to your input!
