I had my period the 11th to the 14th and Glow says I'm suppose to ovulate the 27th. I've not had any discharge hardly at all but I have been cramping some and my uterus is tender. Feels like a pinching or stabbing pain under my belly button and to the side of it. Does that mean I may still ovulate? I had a d&c in March so this period is totally different. I've been using opks but they're all still negative. I'm so confused!
