Mrs. Duck - you look beautiful!!! Home stretch!
Melly - for me, many months I had watery CM instead of stretchy. As another said, sounds like you are in your fertile window.
Flou - the tests that you are having are what I had as well. My ultrasound did show some retained tissue from a previous loss. Initially they thought it was a polyp. I had a hysteroscope (basically a d&c with a camera) and they removed everything. I took 6 weeks or so off to heal and got pg with this baby on my second try after surgery. I hope it's that simple or less for you. The good thing about normal tests is that, so far, nothing is wrong. Maybe just a few bad eggs.
Buttrfly - I ended up buying the Clear Blue digital OPKs. They are quite a bit more expensive but once I knew my cycle I only used about 4 a month. For me, I needed the clarity of a smile or no smile.
Hope everyone else is well!
