Im around 13dpo, the top 2 tests are from monday, the 3rd is from Tuesday and the 4th i just took like 20 minutes ago. I spotted on 11/12dpo and a little brownish pink today (13dpo) after a BM. My hcg level at the docs yesterday was 37 and my progesterone was 9.3ng, they say that between 7.4-12ish I think is ideal for progesterone. But my hcg level puts me at 0.2-1 week pregnant. I go for a retest today to see if my numbers doubled, but if im still getting a positive with a number that low, do you all think i did double? Are my tests getting lighter? I'm driving myself mad worrying about a miscarriage....
