Can someone help me - I have been taking Clomid for 3 mos - I am at day 31 now - at least 1 to 2 days late per previous 2 months - took an hpt today and it came out positive - ran out and bought another one to confirm - took it half an hour later and it was negative -which one do I believe - is it possible to retest to quickly?

The first one!!!

You can never get a "false positive" The HPT will only say positive if it detects HCG, and the only way to have HCG is to be pregnant.

Most tests require that you wait ATLEAST 4-5 hours without urinating before taking a test to allow for HCG levels to build up. The second test may come up negative because there wasn't enough HCG in your urine!!!

Congratulations... Now get outta here and get to the doc.. you have some pre-natal vitamins to take!!!

have a H&H 9months!!!

Send some baby dust my way!!!

Different tests measure different levels of HCG and it could be that because it is so early on, your HCG levels are just starting to show up and the second test may only detect them at a higher level. I agree with the second response in that you probably didn't allow your urine to get concentrated enough and the urine was 'watered down' per se. CONGRATULATIONS!!!!!!! Send some my way... I am testing on Sunday... I need good vibes and tons of baby dust!
