There are some ladies who love intrarosa and others not much. Try putting Intrarosa in search engine. There has been a number of posts regarding this product. My guess is Intrarosa takes a very long time to work (4 days is definately way too soon) and has a similar trajectory as vagifem. Have you googled to see reviews on the product? You might get a better insight as to side effects. Good luck and hope you get it sorted soon.
