Is this really my period?

It really depends on the woman. In this case you are probably irregular and your going through a lot of hormonal changes. The crying in the bathroom, and headaches can be because of the hormonal changes. Everything is okay. Its normal. & I think that your period maybe be coming near. If you are worried about the amounts of pain with your period you should see your doctor or if your regular begin to take Advil two days before your period so the pain will decrease.
