But I don't have any regular tests, and I know clear blue digitals are not very sensitive. So I wanted to see the strip for myself. I have heard that they always show a faint positive, but I have also heard that they don't. From what I have read, clear blue digital smart countdown DOES NOT measure LH. So this test measures HCG only. The top one is today, and the bottom one is yesteeday. I feel like today's is darker. 😖🤔 not sure what to think. Prob get a FRER in a couple days if I don't get AF.
