Hmm, so this is just me but I think Tian's body finally relaxing after all the years fighting alone. I mean stress can make your period stop. I know because there is 6 months my period stop and then it come and boy it hurts so much. So Tian don't worry, it just your body told you, that you finally in safe place. But yeah, period suck and I wish there is an option to not having it.
