Early pregnancy symptoms?

Kasi

I’ve been having pregnancy symptoms a lot lately to the point my coworkers are telling me I am, but I tested awhile ago and the test had dye run but showed a positive but I’ve taken a few other tests a week or so later and I get negative? TMI last night I had thick sticky white/clear discharge what’s going on I am on the patch birth control but my coworker was and still got pregnant
