Low progesterone w positive test

My dr has been checking progesterone the last couple of weeks and it was 2.5 last week. She told me I didn't ovulate but then I had sore breasts and spotting and just took a test today (14 dpo) and it's positive. I went for hcg and progesterone today and get results tomorrow. She mentioned I either need supplementation for progesterone or will have a miscarriage due to some issue causing low progesterone. Anyone go through this? :-/. We have been trying for 8m and would have started clomid next cycle...
