Need help

So this is my calendar

My periods haven’t been normal my last period in August I had 2 full days with a medium period the rest of the time it was light pink spotting I’ve been very moody more than normal my nipples are sore and they are never sore til literally 3 days before my expected period which ain’t due yet I’ve been feeling nauseous bloated gassy really bad fatigue pelvic pain hip pain and cramps around my uterus area. I took a test and got a negative 😭 since my ovulation day my body has been feeling weird like I noticed feeling weird on the 25th of August since then the weird feeling has gotten more into depth. Could I possibly be pregnant and just took a test too early or what?
