M.H.
My cycle never really got regular again. I am pregnant with my second, but it took some real monitering. One month I would be 26 days, the next, 30. Get a basal thermometer and take you waking temp every morning. The directions will tell you how it works, but you will be looking for a temperature spike. this is the best way to predict ovulation. The tests only work if you take them at the same time each day and on the correct days. I know you took them for 7 days, but with such an irregular cycle, you could have still missed your day. As for missing your period, you need to talk to your Dr. about that. Your right, if you are not ovulating, not much you can do! I wish you the best of luck, don't let yourself get too frustrated. It will happen with patience.
