We are TTCing. I bought a multipack of Wondfo OPKs and HCGs.
I got a postive OPK on Saturday, I just had my IUD removed earlier in February.
Because I had a BUNCH of HCG tests, I decided to take one, when I know it would be negative, to see what a negative looks like on the Wondfo.
I didn't see anything at first, but when it dried, it definitely left a line. For an evap line, it was pretty convincing, I could have swore it had color. But I know I'm not pregnant. So that goes to show that you can't look at it past the 5 minutes.
Anyone else have the same experience with Wondfo?
