Vaginfem Suppositories

My doctor prescribed VagiFem Suppositories for vaginal dryness. I am 59 years old and in good health. I have not had a hysterectomy. My concern is the side-effects as far as estrogen and weight gain are concerned. After filling the prescription and reading the potential side-effects, I'm afraid to try it out.

I would appreciate your input/advise so I can make an educated decision on whether or not to try it.
