progesterone cream questions

I've only used it for a month, but I was wondering when I'm supposed to notice changes. I got the compounded kind with a prescription because my blood test showed low prog. and my cycle is backwards (I feel pretty good when I bleed but horrible when I ovulate--physically and mentally.) The only change I've noticed is less bloating (yay!). Also, what kind of negative side effects should I be looking out for? When should I expect my body to start making its own progesterone again? Thank you!!
