I had my period 1 day late from the predicted date of flo. so, that's okay. it's normal. But, I had a medium flow which is kinda unusual to me since I bleed heavily especially when I'm on my 2nd day. This time, I didn't fill any of my pads. What's weird is, my period completely stopped after 3 days. so 4th day, no more blood. Then when I woke up this morning, 5th day, I had a blood stain in my undies, like a spat of blood. I wore napkins again, I checked, no blood at all.

Is it possible I am pregnant or my body and cycle is just being crazy for this month?
