this month my period was late, by almost 2 weeks, when i did get it it lasted 2 days and was no more than light spotting with mild cramps. i have also suffered fatigue, mood swings, constipation and sore breasts, i have taken 5 home pregnancy tests all say negative. i have a doctors appointment tommorow but know that a blood result may take a few days to come back, can any one help? could this be pregnancy or a sign of something else?
