Hi I began using a progesterone creme about 2 and a half weeks ago. The past couple of months I had been having terrible episode of severe fatigue, nausea, dizziness, anxiety, depression, and feeling terrible. This was a pattern every month around the same time. I began the creme and noticed that my sleep had drastically improved and felt somewhat better. This month when the cycle would begin I started to have some of the same symptoms but not to the severity. This month I'm very dizzy and lightheaded at times and emotional. Could the creme be causing this and how long will it take to notice a really big difference from using the creme?
