I have pcos and just recently started the clear blue ovulation test this week. I never have been able to tell when I've ovulated or been able to track it. I don't ovulate as well or as often as you should. My doctor told me to try these to help keep track or see if I was ovulating because I have been wanting for so long to try and get pregnant .  Sunday and Monday I didn't have a positive result, but today I took a test and got the little happy face result which means I'm ovulating!! I was so happy! It gives me a little hope that someday soon I'll be able to get pregnant 😊 also the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> helped me figure out what days to test on. Love this app! 😊
