Hi, My 12 Year Old Daughter Just Started Her Period

Hi, my 12 year old daughter just started her period 2 days ago. I have been giving her Pamprin, and she says it is screaming pain. Can I give her my 800 mg ibuprofen by cutting it in half? or can I give her
excedrin migraine? I don't know what to do. I have tried to talk her into drinking tea, and she won't!
well I went to the next page, and I see I have to pay, so being that I am below poverty level, I guess my daughter has to suffer until tomorrow when the doctors office opens up. You really shouldn't say that this is free, because that is how I looked up!!!
