low progesterone

So my husband and I have been trying to conceive for about 6 months. I know that isn't too long but I am a very proactive person when I am trying to do anything so I went to my doctor to just make sure I was over all healthy so I would know we weren't facing a brick will in our journey to conceive. So my doctor set up some labs for me to check my thyroid and my progesterone. I got the results back today and apparently my "progesterone is 2.7 but they want it above 6"....so this freaked me out honestly. All I have ever wanted even since I was really young was to be a mommy. I went back again for lab work today and I am supposed to hear back tomorrow. I am just hoping this is the kind of thing that can be treated with a supplement or something easy and not a long,expensive, emotionally draining thing.
