BFP’s and Low Progesterone?

Hi ladies! I just got my BFP!

Started testing at 9DPO and got a vfl, the next day was darker and then darker again today. I also took a First Response! I have low progesterone (7DPO was 5.6) and just started taking progesterone pills today at 11dpo. My hcg is at 46. Any success stories with low progesterone and BPF’s?
