Since you have had a few kids your cervix will probably always feel slightly open. I know mine does. JM has an article on how to tell the difference between EWCM and semen. Here is the link.

My guess is it was creamy CM that you see before you start having the EWCM. A lot of gals will have creamy lotiony looking CM and then later get the EWCM. I usually try to bd regularly (I try not to skip more than two days) until I start seeing EWCM or get a positive opk.
Your temps are still pretty high and you are pretty early in your cycle still so I think you may have a little longer to go. Of course, you haven't been charting long so it is hard to say what is normal for you.
