I would NEVER use Pregnow again. I had a false positive Pregnow Hpt last cycle at about 12dpo (from memory?) and it was a faint 2nd line but clearly there. I used the test correctly and dipped it in the urine for the correct amount of time and didnt' exceed the marked line etc etc and the line came up immediately. I was sure i was pregnant! Then got the BT done 3 days later and turns out I wasn't even pregnant very upsetting. I do believe they aren't very reliable.

HOWEVER, when i actually was pregnant in November, I got a BFP with a Pregnow test (3 actually) and BT confirmed i did have hcg in my system but i had early m/c so yeah, i am very confused about pregnow because i did get what were actually true BFPs the cycle prior.
