Hiya, I have my scan today and I'm really scared. To put my mind at ease I peed on an OV stick as I don't have any HPTs..and got a negative result. I used one at 6 weeks and got a very strong positive. I know they're not meant to be used as HPTs but I just wnted to put my mind at ease. How reliable are they? And does HCG reduce slightly as the months go on? Thanks.
