6 days late for AF —negative tests!

Can someone give their input on my situation? I’m currently now 6 days late for my period. I’ve been taking tests like crazy, but they’re negative. Although there’s been like 2 first response tests that got I super faint line.(there was pink to it at the bottom of the line). I’m having pregnancy symptoms that i normally wouldn’t get for any period of mine. I’ve been peeing frequently (sometimes a lot of urine, sometimes big urge but not a lot of urine), constipated, EXTREMELY Gasy, super hungry (been craving sugar and also Wendy’s/Swensons), a little bit of nausea but not much, my boobs are starting to hurt, SUPER TIRED, and a little crampy but not anything strong, and it’ll always be on one side of my pelvic.

*I also have been having an increased amount of discharge. So much that I thought I started my period a few times*

—-Please help! Thanks in advance❤️——
