Need help

Karley • I'm a Wife and mommy of 2 👨‍👩‍👧👶

Ladies I'm so confused this cycle. Ive had stomach aches and ik this is TMI but ive had a few days of diarrhea like last weekend. And had like funny smells and weird tastes in my mouth. Last night which is 12dpo I had like pressure in my uterus then after I had some tender breast and cramps I thought the pressure in uterus was so strange! I took a test today which is about 13dpo and it was negative.

What is the pressure in uterus means?

Like I feel I could be pregnant but I dont want to be too upset if it not
