I started using this app in July after I got my IUD removed. It has been an incredible tool to help me keep up with what's going on with my Body. GLOW predicted my ovulation last week as did Ovia. I had a questionably positive ovulation test last week. My husband worked extra late last  week and I was so disappointed because I believed we had missed it. I had some right sided pelvic pain this morning so I took another ovulation test and it was unmistakably positive. 😍
