I honestly don't know hun, hope you get the answer you want today

About the false positive thing - I set them off all the time. Twice now I've been rushed to hospital because I'd gotten BFP's, then gotten severe abdominal pain and bleeding a week later, which was always diagnosed as a possible ectopic until they blood tested me, and found that I was never actually pregnant. Long story short, an excess of hormones, not necessarily HCG, can set of HPT's but NOT a blood test. But that was for me, when I was going 8 months between periods.

Just to muddy the waters for you
