yes they have creams, which have the exact amount (30) that your ovaries produce. be sure not to get the wild yam ones, half the time there isn't any progesterone in them.
You need to see your doctor for a progesterone blood test before you get a cream. too much progesterone can make you sick.
Can you buy progesterone over the counter?
I am having the same problem. Was late for a week, and have been spotting for 7 days now. My progesterone is low and I need to get on the supplements tonight to stop the spotting and kickstart my period again.
Have your progesterone level checked - that's how you just spot like that. Hopes this helps
