No period after progesterone? Negative pregnancy tests? Am I infertile?

I went off the pill in February 2011 because I didn't want to pump any more chemicals into my body. I went through a bought of depression and disgusting acne when I went off it so I decided to go back on it last week. I had protected sex with my boyfriend in May when he was over and all pregnancy tests I have taken at home and at the gynecologist have all been negative, obviously. I was (and still am) late on my period by over a month so my doctor said it would be best to go back on the pill. She put me on progesterone before I could start back on the pill and said it would take latest 7 days to work. It is now day 8 and there is still no period. What does this mean for me? Am I infertile? Did I screw up my ovaries? I am not really sure what I should do and I am afraid to contact my gyno because I feel like there is something wrong. Help!
