So, my question is about the sensitivity, I was wondering, if the sensitivity says like 25miu, does that mean that in order for ANY line to appear, no matter how faint, your HCG level must be above 25? I was just wondering because I got a faint positive on a frer which is like 15-25miu on 9dpo, and on 12dpo I took a boots own and got a line of similar darkness (just a little bit darker) which is 50miu, so does that mean that my numbers must have at least doubled in those 3 days or am I seriously wrong?
