Confused needing help.

Simone
So I have been getting ewcm for three or four day. So me and hubby bedded Friday and yesterday. He works out of town during the week so could only start bedding Friday. Anyways. This morning checked cm and had a lot of creamy white looked kinda like foam this evening its dry. Does that mean I ovulated either Thur, Fri,or Saturday? I have never had so much cm before but this month I been using mucinex with just guaifenesin as active ingredient. I know everyone is different just trying to get some insight.
