Super tmi ! Period late one day odd discharge

My period was due today but it didn’t show but I run between 26 to 29 days lately ! I’m hoping I’m pregnant tested a few days ago dollar test it was negative, now tonight I was going potty and I never have discharge before my period , we have been trying for two years . I’m so trying not to get my hopes up Bc my period always ends up being a day or so late ! Ugh . I don’t really have any symptoms besides a little constipation , and tiredness , but I have a two year old so that could be why . Anyway picture of my odd discharge below I’ve never had anything like it ? I hope it’s from

Possible pregnancy!!! Prayers and no i haven’t had sex or anything I’m on vacation with my family
