Amiella, i know what you mean, as I had the same things happen to me this month. I got egg white CM and then watery before my OPK showed up with a surge.

I have just purchased the book 'Taking charge of your fertility' and it is wonderful. It basically states that CM or Cervial Fluid is THE MOST important thing to keep track of.

I like you, have started on Preseed, in the hope of improving the environment for the little swimmers! I also take B6 and drink grapefruit juice and LOTS OF WATER and try not to drink TOO much milk, all in the hope of improving the Cervical Fluid. I am going to try Robotussin next month also which thins the CM. I must say that I DID notice an increase last month, but quality is important too!

I would be very interested to hear what others say too. The very best of luck to you!
