Menstrual Cramps

[Jollysox]

I work at a middle school, and I have girls (mostly sent from PE) that come to the clinic smiling, energetic, etc. They in no way look like they are in any acute distress. Asking to call a parent for pick up due to menstrual cramps. When I call a parent, and the parent is willing to come for pick up, I have noticed that other girls from the same class come to the clinic with cramps, and are asking to go home. Do you all just call a parent and let them decide? I want to avoid sending the message that I will automatically call a parent. Especially if you just say this, or that.
