Possible side effect
I'm really glad I found your site. I was Rx'd progesterone cream for 'pms' which I applied on day 15 till first day of menstrual cycle. But, 7 days later after finishing my menstrual cycle, I got another period! Not good.
Now I see that this is a possible side effect. I don't like how it messed up my hormones and feel like my doctor off-handedly Rx'd this for mild pms not considering the possible side effects that this might wreak on my body which is already very hormone sensitive (I have low thyroid and low cortisol). I tried using the 'pill' before and it made me feel horrible and also threw off my cycle. I'm not touching any HR stuff any more. Thanks for the clear and helpful information!
