Pregnant??

Hi this is My first ttc. And also the first time i'm using glow. I think i'm pregnant but i'm scared to take a test because Its 5 days untill My period. But i have three kids before. I can feel a swirling feeling just above My pelvicbone. I also got Bert soar brests and i'm nautios every morning and every evening, My pants has gotten just a bit thighter around the hips??? Any feedback. What do you think of this?
