My last regular period was like October or November, it lasted like 4 days and I'm always pretty heavy. In December I was like 7 days late and it only lasted 2 days not very heavy, this month I was late like 4 days and lasted 1 day not very heavy and I felt VERY tired and SUPER weak not to mention nausea and dizziness. Im losing weight but I'm still eating the same I'm actually hungry like every 2 hrs but I seem to be losing weight not gaining it. Oh and I have like hot flashes... A LOT!! What could it be? Could I be pregnant?

You need to take a pregnancy test and schedule an appointment with your doctor. Sounds like something is going on... could be a pregnancy, but you won't know until you take a test and/or see your doctor.

Best of luck :)
