Ovulation Question

According to my app I should have started ovulating between July 17-18th. I have pcos and endometriosis and went off all my medication in April and had my first period July 2nd. I have started taking Clearblue advanced ovulation tests July 9th. I got three days of nothing and then today marks 10 days of flashing smiley face which means high fertility. Has anyone had this happen to them before? Should I keep testing? My cm is really confusing me too thinking I will be leading into ovulation soon but I feel like I keep getting my hopes up.
