I have been using two different brands of OPK at the same time (there is a reason I'm not just obsessed!!).
I have been testing twice a day for the past couple of days. One brand (Confirm) now says that I am having an LH surge as the test line is now way darker than the control line within the first minute. The other brand (Fortel) isn't even registering anywhere near a positive. Infact after 5 minutes you would hardly even notice the test line. I have been using 2MU and then again in the afternoon. Using same urine sample for both tests. Yesterday the test line on the Fortel line was a bit darker but has lightened up today. The Confirm brand is still ultra dark. I am guessing that I have ovulated but wonder why two different brands should be so different.
If I was only using Fortel I would assume that I hadn't ovulated or that the OPKs don't work for me. The Confirm brand is telling me something completely different!

Has anyone else ever found this?
P.S. I have fallen pregnant in the past while using both brands.
