Provera for Short luteal phase. Help.

I was prescribed provera 10mg starting day 14-28. I usually ovulate day 18-20 and I started my prescription on day 14. I am not sure if I ovulated or not... but I started to get a surge then it never got darker then got lighter as Days past. Has anyone been prescribed this? My luteal phase usually only lasts 9 days then I get period.. which is what she has me trying it for. I would love some insight! First pic is this last cycle. I am on day 17 now. And below is last cycle when I know I ovulated.
