I began taking Garcinia Cambogia about 6 months ago. To date have lost about 22 pounds---but would like to lose another 15. However, a few weeks ago, I had a week of post menopausal bleeding (after 25 years), which led to a D&C and Hysteroscopy. My Doc says everything looks good, but advised me to stop taking the Garcinia. Aoes this sound valid?
