Late with symptoms but no BFP

Hello. So I'm late usually AF is pretty on time but now on day 36 of my cycle idk. I've tested about 10 times in the last two weeks and all bfn. Around the 26th I had really creamy thick white discharge, and now it's just a lot of discharge mostly clear. This morning when I wiped it was a little pink but right after that it was clear. My period was due around the 4th. My emotions are kinda all over the place, lower back pain, wanting to eat everything and then completely feeling nauseous half way through and the smells oh the smells. Idk I'm hoping for a baby but after 6 months of trying I'm ready to give up. ​​
