Renstar - congrats on the BFP - it's always best to wait til FMU to test as it's the most concentrated.

When are you testing again? Please try to hold off for FMU so you don't stress about it.

FYI I came across some interesting research a while back that said that women can have small amounts of HCG in your body even when not pregnant but it's usually not enough to trigger off a test. An exception to that is if you are perimenapausal when it can be high enough to test positive even when you are not.... but a blood test would be negative. Even women past menapause can have levels of HCG in their bodies.... it's really weird. This is also pretty rare I believe.
