Have any of you looked into checking your progesterone levels?

I was informed by a nurse that a lot of women suffer low progesterone which can be the cause of multiple miscarriages seeing that you need this hormone for your pregnancy to progress. If my levels are low, they will be giving me a cream and or pills to take to make sure my levels remain ok throughout my pregnancy.  Wanted to share with you guys just incase anyone was having the same problem.  Comments welcome! ??
