Progesterone didn’t start my period like before??

X

So the last few months I’ve been taking progesterone to start my period... my first time taking it was once a day for 10 days and my period started about a week later. Each cycle I take this I take less pills and my period is starting sooner and sooner. This cycle I ended up taking all 10 and now I’m about a week and a half out and haven’t even started spotting. A few days I was really bloated and cramping and I’m really breaking out but that’s all calmed down. Why wouldn’t my period start?? Do I need to take more? Has anyone had this before??
