Wondfo HCG test

What is the general consensus on the Wondfo pregnancy tests? I'm 12 days past a positive Opk today, took a test this afternoon (clearly not first morning urine) & it was negative. I have had mild cramping off and on at 8 dpo, I'm exhausted and could fall asleep at drop of a dime (but I have 2 young children who exhaust me). I feel like I could probably make up any pregnancy symptom in my mind at this point. We had sex 2 days before I got a positive Opk, and one the evening of pos OPK because I REALLY want to be pregnant at this point. So I feel like my chances were the best yet!
Anyway I'm wondering if the Wondfo brand is the most accurate? I have a more sensitive test I may use tomorrow first thing in am.
This is only my 3rd cycle trying but I'm so frustrated! Didn't even have to try with my 2 boys! And at this point I'm getting desperate even for a 3rd healthy boy!

REmember, it takes fully fertile couples doing nothing to sway, 3-6 months on average to get pregnant.

BUt that having been said, I think 12 DPO can still be too early for some people. 14-16 dpo to be certain.

Emilee wondfos aren't great. You are better off investing in Frers or the digital hpts. I got way too many false positives. Never buying them again.

Yeah even tho Wondfo makes a great OPK, their pg tests seem to be a bit less effective - they do work, just that thye aren't as sensitive as some

I agree. I LOVE their OPK's they caught the 2day partial positive on the upswing, 2 days of positive, and 2 day down. Very sensitive so you know you wont miss it. However their HCG tests leave much to be desired. They are not very sensitive at all and it took me 15dpo for them to register positive. I grabbed one of the OPK's as they can be an indicator of a pregnancy when you KNOW you aren't ovulating and that thing was darker than the HCG test was.

In their defense though, ~I personally~ prefer people test later rather than sooner to avoid upsettedness over false negative pg tests and also heartache over chemicals. Chemical pregnancies happen all the time and I feel like people are reading way too much into chemicals and going to all these lengths after having them, when it's 99.99% of the time just that it didn't work out quite right and wasn't meant to be. (and not trying to diminish anyone's experience having a chemical in any way - they suck, but they do happen quite often and always have - it's just now we have the technology to know about every one.)
