CB and Wondfo

Hello! This is my second month TTC and something weird happened. I have been POS because that's my life now lol and yesterday I got a flashing smiley face on the CB in the morning, negative Wondfo.Last night I tested again and same thing. Last month I got 5 days of flashing smileys, to my surprise, this morning I got a solid! We DTD because I won't see my SO until tomorrow, but I also took a Wonfo and it was negative. Which one should I trust? Does this happen often? Help!

Go off the FIRST positive of any brand. You can get pregnant with an attempt that is too early, but never one that's too late, and since you can have both a false positive and a false negative on any test, it's totally possible to be waiting around for the second test to go positive too but then it never does.

And yes, it does happen. Some brands are more sensitive than others and so will register positive sooner than the other brands do.
