Could Frequent Urination And Mild Cramping Be The Symptom Of Pregnancy?

I HAVE BEEN OFF OF MY BIRTH CONTROL PILL FOR ALMOST 2 MONTHS, AND MY HUSBAND AND I HAVE BEEN KIND OF TRYING TO CONCEIVE (WE FIGURED "WHEN IT HAPPENS, IT HAPPENS") WE'RE NOT REALLY TRACKING IT. ANYWAY, I AM DUE TO START MY PERIOD IN 7 DAYS, BUT I HAVE HAD A SLIMY DISCHARGE SEVERAL DAYS AGO, AND I NOTICED THAT I HAVE BEEN URINATING MORE, AND THE PAST COUPLE DAYS, I HAVE HAD MILD CRAMPING (IT'S KIND OF LIKE MENSTRAL CRAMPS.) COULD I BE PREGNANT, OR I AM JUST GETTING STRESSED AND READING INTO THIS TOO MUCH? WHEN DO I TAKE A PREGNANCY TEST? CAN YOU PLEASE HELP ME TO EASE MY MIND?
