You don't say whether you have hypo thyroid or hyper thyroid, or whether you are significantly overweight -
Is your doctor trying to treat your thyroid disorder?
I am slighly overweight and yea my docter is treating my hyperthyroid disorder
I mainly just want to know if this is normal for someone with these problems...
If you're hyperthyroid, then yes it can cause you to have irregular or no menstrual cycle.
