Hi over the past few months I have had numerous positive ovulation tests on various days I've had no period in this time and have only had a couple of negative ovulation tests. I have also taken pregnancy tests throughout and all been negative. Any idea what's going on? Am I ovulating or not? Im so frustrated :(
