I am currently taking generess fe. I take it at night before bed because I tend to get nauseaus from birth control. Lately I have been having what seems like 2 period per month, I know it is break through bleeding, but it is lasting days. Today I experienced the worst dizzy spell I have ever had for 30 minutes at work. I know a lot of things can be affecting this, I am extremely stressed as a grad student, I work full time, and I'm an emotional eater. Sorry so much information, but I need help and I am searching for a new doctor as I type this.
