I had my period for 2 days but on the second day it became lighter until gone. On the next day at around 1pm it resumed but just a brown discharge then became lighter and spots like when my normal period should last for about 5-7 days. After 2 days, i got a pregnancy test but came out negative. Now im experiencing pimple breakout, low back pain, abdominal cramps at times, and some itchiness on my thighs and back and feeling sleepy. Is there a possiblity that I am pregnant?
