I have had irregular cycles after getting off of birth control almost two years ago, and thought that I wasn't ovulating because my husband and I still haven't gotten pregnant. Went to the dr. a few weeks ago and she recommended doing blood work on certain days to test for hormones. I have been trying to use opk's for the last few months during the days glow told me I was ovulating, but always got an "O". Finally after 5 days of flashing smileys, I got a non flashing smiley, and my peak day is here!! So excited to keep trying for baby #1 😊
