No period, negative tests?

*EDIT*

I just took a cheep test. I’m so close to giving up. 😫 I don’t understand.

My period was expected to end today but I still never got it. I have taken 3 pregnancy tests since the first day of my missed period. All clearly negative. I am bloated, I have white creamy cm, low and soft cervix, moodiness, smell sensitivity, headaches, I’m gassy, itchy/full breasts, nausea, and a pressure behind my belly button and under my belly that is really tight. (It feels too tight to push to poop but I still poop just fine.) *tmi* usually before my period I smell different and this tells me my period is coming, but currently I have a fresh/no period smell. I just want to find out if I’m pregnant or not, I’m starting to lose hope considering the negatives. Any thoughts/advice?
