Today and yesterday I had yellowish egg white cm that is very snotty like. One or two days bbefore expected period. Took a test a few days ago and there was a positive full and of color but some say it was a evap. The other one I took (purple) I think I see a vvvvfl on it. Any tweakers? Or anyone else see it

-ps sorry for the horrible pic cause of flash.
