I'm freaking out. Okay so I got my period by it was cut short.. Like really really short. Normally I have it 5-7 days. Not this time it was like 3-5 days.. And now I've like a huge cramp like feeling alon my waist line and right side.. When I sit up it feels like I'm stretching every muscle in my stomach, barely even moving, I'm laying in the fetal position because it doesn't hurt as much. Is it supposed to be this bad.. And what do I do..?
