Hi I am currently using the OVWatch I am on my first cycle using it I am on cycle day 4 so I have a few days to go to see if it will say when I am ovulating yet. I wear it about 8pm to the time I wake up. I always do the test mode to see if it is working correctly it only takes a few seconds. I am excited to find out if it works as good as it says. Thank you Heather
