Hello. I Am A 22 Year Old Female. In October

Hello. I am a 22 year old female. In October I had a gynecologist diagnose me with PCOS. My fiance and I have been ttc for 7 months now and I have been regularly testing my ovulation with tests strips. Normally theyou are positive for 2-3 days then get darker again. This time I am currently on day 6 of positive lh tests. And I also took a hcg test which came back negative. My family has a history of ovarian cysts, I am wondering if that could be what is throwing off the tests or if it is something else. Thank you
