My period ended two days ago. It lasted about 6 days with a medium flow for the first three days but was really light pinkish for the next 3 days. The day that I got my period I took a pregnancy test that was negative and then immediately got my period. It's been two days since the pinkish spotting stopped and I have menstrual cramps. My cycle is fairly regular but my period that just ended was 5 days late. Could these cramps mean that I am actually pregnant?
