Hello,
HPT's vary in their sensitivity and thus the more sensitive ones could read positive while others negative. To know for certain I'd recommend you have a blood test drawn for your hCG level.
Best regards,
Dr. Downing
a positive is a positive! the positive results were probably more sensitive tests than the negative. There are false negatives but not false positives....for the hpt to be positive your body has to be producing the hcg hormone there is no other reason for it to be positive unless you have hcg in your body
sounds like you were pregnant, it may still be a chem. pregnancy, OR maybe you tested w/very sensative brands. sometimes the dr's office doesn't use sensitive enough tests.
give it a week and test again! Good luck!
