ok heres the deal, two moths ago a had light pink/ few drops of blood about week/two weeks or so after my period, i thought i best leave it until later to do a pregnancy test if i miss my period... HOWEVER, last month i did get my period but it was only three days long (usually 7-8 days and heavy) and lighter than normal (though not excessively light) within that time i have been moody/snappy, my boobs have been sensitive, headaches, REALLY tired, emotional (like a roller coaster, so much so its making me emotional about it) ever now and again i feel nauseous, dizzy... im now a little worried as the short period could be an indicator of something else. (im 29 me and my bf have had regular unprotected sex)
