Hi Nita,
Your daughter may be some of the few that cannot tolerate these hormones. She can change them of course and there is a helpline for women on HRT called The Amarant Trust and I think a quick call to them would be advisable....
She needs to get all the knowledge she can of all the different types available.
The Amarant Trust no:
01293 413000
and their site is here....

She may well be just wiped by the bug she's had, there are some nasty little germs around at the mo :-(
Best Wishes to You Both
B :-)
