So I have PCOS but since I had been on birth control it regulated my period, so I haven't been on it since last year. So recently a week ago I ended up spotting on the 12th-14th. My period was due on the 19th or 20th and still hasn't showed. Could I be pregnant? I have taken 3 test and they are all negative and my flo app says I have one more day then I can test should I wait till tomorrow and test again, or should I just wait for my appointment Tuesday?
