Egg white discharge

My period is due in 7 days. Yesterday I felt like I had a lot of watery discharge & random cramping through out the day. Today I had egg white discharge. I am new to tracking & haven’t paid too much attention in the past. But do you normally have a week before your period is due or did I ovulate late or possibly pregnant(don’t want to test until after late period) The past few months I’ve been ovulating around the 20th.
