I have a fertility monitor and it did not work for me. I also have pcos and I think maybe that's why. I used it for about 3 months and only received highs and never any peaks
. I know I am ovulating because I am seeing an RE and taking meds for ovulation. I decided not to use it this month and just stick with opks. It seemed like I was still having to use opks with the monitor since the monitor would never pick up my peak and I was having to spend tons of money on 20 test sticks a month plus $$ for opks. I think this month has been a lot less stressful since I haven't been using it.
But I would like to say that I hear most people absolutely love it. I am considering selling mine, but I may hold onto it and reset it and give it a couple more go 'rounds.
