I've asked something similar in conception but I thought someone here might have some experience. I am on a treatment plan for recurrent miscarriage, increasing progesterone after bfp. I have had extemely faint lines on FR tests yesterday and today (14dpo). I have never tested earlier than 16dpo when I always had good strong lines. I am supposed to increase the progesterone if I get a positive bfp but the line is so faint and I really don't want to keep taking it if it's not happening. Has anyone got any experience of this. I have seen a lot of negative tests in my time so I am sure something is there. I have infertility diagnosis too so my expectations of being pregnant are very low.
