When I was on the pill a while back, I would get some of these symptoms during the month but nothing severe. It only lasted a little while and once I was on it a couple of months, I was ok. My breasts were sore more then usual but that was me. Every woman is different. Since she is on the pill, she must have a gyno. Tell her to go talk to her gyno about her problems and I'm sure they will be able to tell her what's wrong. In the case of this post, not too many people are going to be able to give you definite answers. Only a doctor will give you that kind of reassurance. Good luck.

Where you can always find me
And we'll have Halloween on Christmas
And in the night we'll wish this never ends
We'll wish this never ends..."
