has anyone else taken the medication given to them by doctors to get their period?

So my husband and I have been TTC- I got off birth control in October and still have not gotten my period but I recently got blood work and everything came back normal. My Doctor said if I still don't get my period in a few weeks that she will give me a medication which will bring on bleeding for a period to start. 
Has anyone else taken this before? Does it work? Do you have any side effects or does it feel like a normal period?
