Progesterone levels are low

Hi everyone!!!!! I got a positive on my 1st beta today and I'm so happy. I can't believe I'm finally pregnant after all these years !!! The only thing that worries me is that my progesterone levels are at a 2 when my doctor said they should be at 10. Now I'm on edometrin suppositories 3x a day and 1ml of POI daily. Has anyone else experienced this?
