What you've described is very similar to what happens to me up to 3 days before I ovulate. Up until this month, I've been basing my O date off of those two signs alone. But then I read that you can have what seems to be fertile discharge up to 2 days after you O. So, I started monitoring my temps this month, just so I have another factor to base my O date on. I'm only on CD11, and I haven't ovulated yet. Yesterday, I started getting my pre-O symptoms just like you described. It will be interesting to see how my temps coincide w/ my symptoms.
So, to me, it sounds like you are either getting ready to ovulate or you just did. Hope that helps and good luck!!
They say implantation can occur 6-12 days after ovulation. The clear stringy, egg white consistancy, discharge is a sign of ovulation. It sounds to me like you are having ovulation symptoms. Take care.
