I feel... "off"

Sadai🌻
So I am currently about 9 DPO (about), I had been feeling super tired.. light cramps.. swollen and sore breast... but today around 10:30.. aaaalllllll of my symptoms automatically intensified. I bleed less than half a drop.. having weird yellow CM? My body is extremely achy and tired.. hot flashes.. peeing literally every hour or every 30 minutes sometimes..  a little nauseous.. headache which sometimes pounds😩, boobs still super sore with tingling feeling, cramps a little more intense and weird sharp like pinching feeling.. my legs hurt so much. Did anyone experience the same before they got their BFP? Could I just be getting sick ? AF due the 16th.
