I don't think that it is too early to try the Ovulex. I tried it, but it didn't work for me. I have tried it twice now for almost three months both times.
If you are charting, can you post your chart so we can look at them? Do you use fertility friend.com? They make it really easy to post your chart.
I would think that if you take your charts to your doctor, they might be able to tell you if you are or are not ovulating.
Keep in touch and let us know
