Knowing pregnancy is occurring without taking a test.

Darcy
I skipped my period so I decided to take an at home test. Before I did, I remember pissing a lot, during one trip to the restroom, as I was washing my hands I felt a ' knot' twisting around inside my vagina. It didn't hurt nor was it uncomfortable, but it was almost like something happened. Some type of movement.. (I must have been less than 6 weeks pregnant at the time) but it turns out I was.... Is this normal?!, I've asked other women... But they don't know what I'm talking about.... Could it be that I'm just that much more in tune with my body?
