Progesterone pills during HRT

I have had problems with my periods since I was about 26 or 27. I finally went to my doctor when I was 33 and was diagnosed with ovarian failure. She put me on estrogen and progesterone pills. I take estrogen everyday and progesterone day 21-30 of my cycle. I have been on these pills for almost a year and a half now.

I have had a couple of times where my period started early without me getting to day 21. That happened to me in May where I had two periods. I did not take the progesterone when I was supposed to then... basiclly I just started counting the first day of my extra period as day one again.

So then when I got to day 21 of my cycle I took the progesterone tabs as I should for the 10 days. I usually always start my period around two to three days after I stop taking the progesterone. But this time I have not started my period and it's been about a week.

I thought that progesterone stimulated my uterus to shed the lining the estrogen helped to build. Am I wrong? Could I be pregnant? That would be hard to believe though as I thought I couldn't get pregnant. I decided to wait until the next time to see if I start then but I don't know if that's a good idea or not. I didn't want to bother my doctor if this is nothing.
