So here is my cycle tracking of OPKS so far this month. Now I know none of these are positive but I had watched a YouTube say that the generic brand off amazon wasn’t as good as Wondfo so I drank the cool aid and bought Wondfo..Well Well Well...HUUUGE DIFFERENCE E. see cycle day 8 ( today) at 1600 I decided to see for myself and used the same urine sample and dipped both strips.

The Wondfo showed up and the generic brand off amazon barely showed any LH in my system
