My last period that I noticed was 11/26/2017. In December I bled lightly on the 28th but it stopped by the morning of the 30th. New years eve I woke up vomiting, like yellow egg yolk vomiting. I began to notice Brown discharge(no blood) every time I wiped or had sex that stopped appearing by the 2nd. It now February and I did not get a period at all in January or no bleeding. Today, February 2nd I have light spotting, a little red but more Brown. Am I pregnant?
