How early can a Wondfo HPT pick up pregnancy? If you used a Wondfo to confirm pregnancy, what day was it? I have 5 Wondfo tests (and 3 digital tests to confirm), but I'm wondering if I wouldn't be better off picking up some FRER also? I see people testing and getting BFP on 9dpo and 10dpo, and I'm wondering if Wondfo's are sensitive enough to pick up that early?
