I got my period a week late last month and it only lasted 3 days and wasn't even enough to fill a whole pad througt out the three days, normally my period is moderately heavy and between 5 and 7 days. Also I'm nauseous a lot of the time now, my breasts have gotten slightly bigger, my stomach is bloating, I'm constantly hungry. tired and turned on, my back hurts, I'm having dreams where I'm pregnant and I'm now more than a week late for the second month. I took an HPT the day after my last day of period when it was late and unusually light and it came back negative but now I'm not sure due to more symptoms.
