CM keeps changing

V-Lin
Ok. What's going on with me?? My CM was consistent with what my calendar was. It was very watery/egg white like for my fertile window and after that I have been having a dry spell. Here and there I get creamy, I get watery, back to dry. Well I just went to the bathroom and it's egg white again! Very clear and stringy! I've been having symptoms and waiting for some kind of thick creamy CM or implantation bleeding, but it's either dry or watery. Could I still be pregnant?!
