Lupron help

My FET got cancelled last month due to a progesterone spike in my labs, they said that meant I ovulated and couldnt do transfer. So they put me on lupron. She said when I start my cycle which is typically around day 14 to let them know so they can dose me down. I've been on lupron for 14 days and nothing. So I got to reading and I've read ladies dont get their period while on lupron. So im confused, has anyone went through this or can give me some advice other than talking to the doctor which I plan to do tomorrow but just curious if anyone had similar experiences
