Last month I had my period on time, then just under a week later I bled again, except this time it lasted longer and was lighter than my period. My period is now late and i've been experiencing fatigue, and nausea as well as light cramping. I don't usually have any cramps until the day I get my period. All week my cramping has been light, not bad enough to take midol and feels better when I walk around. Sometimes the cramps make me feel like I need to go to the bath room. I took a pregnancy test six days ago and it was negative. A year and a half ago I had an ectopic pregnancy and a possible miscarriage (the miscarriage couldn't be confirmed because of my low hormones due to the ectopic pregnancy).
