Pregnancy symptoms!?

Okay so I definitely thought I was pregnant this month.. right before expected AF I had such SORE boobs, and dizziness and nausea which is really not normal for me. I took an hpt on Sept 27 and it was negative.. My cycle has been irregular but based on the app I was 3 days late when I finally started to bleed on Oct 1. The bleeding was enough to make me believe I was getting AF but then the next day it was completely gone. This is so bizarre because my periods are usually 5-6 days long! My dizziness and nausea has gotten worse over the last few days and I’m noticing I am peeing ALL THE TIME (no increase in drinking fluids) no burning, pain or discoloration so I don’t think it’s an infection. My dr sent me for blood work to check things out (including hcg test).. I don’t want to get my hopes up but do you think I could be pregnant? Any similar stories? I am so anxious.. I hope I get my results tomorrow!!!
