Am I pregnant and did I take a test to early?

So I’m either 11 or 12 DPO. 3 or 4 days away from my period. I took a 6 day early test and got a negative. But I just feel like all these symptoms I’m having are pregnancy symptoms. This is what I’m experiencing.

- on and off cramping on lower abdomen

- gassy and bloated

- lower back pain on and off

- constipation and when I finally go it comes out kinda like diarrhea

- hot flashes

- slight nausea

- severe fatigue

- pulling sensation or fluttering that feels like is happening in my uterus

- had experience sharp quick pain in belly button that goes down to private area

- it’s hard to know about my boobs because I still breastfeed my toddler

- I also sometimes out the blue get really cold but I get more hot then anything

- feels more wet down there and I almost thought I started because I felt a gush but it was just discharge (creamy white)

- lots of headaches

Help ladies what do you think I’m pregnant or did Am I trippin??
