ANSWER™ ovulation predictor & PCOS

So I just randomly picked up the ovulation predictor test kit earlier this week. I tested Monday and it was negative. Look at the pic for tests Tuesday to today. I know you are suppose to stop testing after you receive your first positive but I kept testing just because lol. I suffer from PCOS so that makes it even stranger lol. Hubby and I didn't BD Tuesday but we did Wednesday and yesterday. Couldn't do today due to him being out in the field doing military training for the weekend. Has anyone else experienced this?
