Pregnant maybe?

So for the past week or so I’ve been waking up in the morning with stomach pains and diarrhea. I wake up because it hurts and I have to go and this never happens. My stomach has felt weird all week and I feel nauseated and just so blah. I have also had clear, snotty discharge with no odor. I don’t think I’m pregnant but i saw some women on here posting they had this at x amount of weeks.... i stopped taking my birth control recently and have had unprotected sex since that. should I take a test? What could it be?
