Pregnant?

Ka

Okay so I’ve been having this super weird pressure in my Uterus. Like almost like cramps but not as painful I had my period normally and it came and gone already but I just feel funny! I took a pregnancy test a couple days after my period ended and it was negative but I just can’t shake the feeling. I’ve heard story’s from my family who had their periods normally for months before they knew they were pregnant and I’m just not sure what to do. Has anyone experienced this before? If so what was the outcome?
