I am using progesterone vaginal capsules and experiencing vaginal irritation Is there an alternative?

I am sorry that you're experiencing unpleasant side effects of the progesterone vaginal capsules. I'd suggest that you check out a natural progesterone cream. To use it, you simply rub a small dab twice a day directly to the skin as if you were applying lotion. A natural progesterone cream is really effective in treating hormonal imbalances in many women, so you may want to give it a try. Hope this helps!
