When I was reading for information on the internet, I don't think I read that much information as far as how long it would be in
your system. I did read in
a book, that states that the side effects
would only last for as long as you take the medication. But today, I am feel horrible. I don’t know when to test, because I have been irregular, for the past 6 months. December , I had a cycle for 16 days. Then nothing until March 4th.
