What brand OPK do you trust the most?
I've only ever used wonfos and a store brand. They both worked fine, the ones that I bought from the store were quite a bit easier to decipher but I enjoy being able to take a few a day which the affordability of wonfo allows me to do.
What brand HPT do you trust the most?
FRER but I won't take one until I get a faint BFP on a wondfo. The cost of wonfo tests make my POAS addiction affordable
Which brand do you not trust?
anything with blue dye
