OTC Progesterone Cream

Just went to the midwife yesterday for my yearly check up and to talk to her about a load of symptoms I've been having the last year or two. This is the first time I've seen her in years, as she delivered my first but then due to complications I went somewhere else. Since then I've dabbled with different doctors, but no one really struck me as great. She always listened to me so I decided to try and go back to her. Based on my symptoms, she feels pretty confident I have started perimenopause (joy! I'm only 40). She has suggested I try an OTC progesterone cream during the second half of my cycle to try to even out hormones and reduce symptoms. Does anyone have a favorite cream they'd recommend?
