I am 49 year old and have been suffering with adrenal fatigue and autoimmune thyroid problems for 10 years, I have got a lot of health issues, my main problems are extreme anxiety, fatigue and hair loss.So decided to try serenity progesterone cream after reading so much on it. I am from the uk so that is why I decided using this particular brand. My question is after using 1/2 teaspoon twice a day for just over a week I am feeling more tired, have breast pain and feeling sick.do I need more cream? Or give the cream longer to work. Many thanks.
