help need advice

Hello....normally i dont say much on here but i need someone to talk to!. I am 28 n have pcos n haveknown it since i was a teen. I have been overweight for years but about a two years ago i started changing my life style by working out and eating healthier etc. On n off I have done ovulation tests like clearblue digital n others and I have never seen a smile or anything for that matter to indicate I have ovulated. I am still overweight but and continuously working on this. My periods have been every month for almost a year now but I have never been able to know when I have ovulated. For some reason I started using glow again n it assumed I would b ovulating this week so I went out n bought the Cb advanced digital ovulation test. Yesterday I got an empty circle n today I got a smile which means peak fertility. I also took my bbt this morning which was 97.46 but have nothing to compare it to because it's my first temp for charting. I really felt like this is some kind of joke BC I have never gotten a sign of ovulation before. My husband n I have wanted this for a long time. I just wanted to know if this is the real deal. I know u cant tell me that but maybe u have some insight on how reliable the test is with pcos
