I typically have a very normal 28 day cycle. My last normal period was 11/20, I had unprotected sex 12/3 and 12/4. Since then I have felt nausea, frequent urination, tired and bloated. I took a pregnancy test on 12/18 and it was negative. Later that night I had a light pink spotting which I assumed was the beginning of my menstrual cycle. Since then I have had this spotting off and on for the past couple of days but it has never gotten any heavier. Could I have tested to early even though I took it the day I should have gotten my period and I used a test that detects 5 days before a missed period?
