Two days late and egg shell discharge

Hello, so my period is two days late it's like clock work. I feel like it's not going to come down and I took a hpt yesterday and it was negative but I know sometimes hcg won't show up for days to sometimes weeks later. So when I go to pee I've notice egg white discharge and no it's not ovulation because I've ovulated two weeks ago and went through the whole process of ovulation. My body is like clock work with normal periods. So this has thrown me off I don't want to take another pregnancy test and get my husband and my hopes up so has anyone else had this happen and where pregnant? P.S. Sorry for the pics.
