Crinone Progesterone Gel

Anyone have any experience with this? I have suspected low progesterone and had my day21 bloods done this morning so will know for sure by the end of the week just how low it is but my doc mentioned putting me on crinone 8% gel daily after ov until af or bfp and see how i get on with that. There are a lot of mixed reviews online so was wondering did anyone have and first hand experience with it or any success stories..

Thanks
