I've never used these but I loved the Wondfo ones.

I used these (as well as their ovulation testing strips) & I got a bfp 9 days post ovulation.

I used these when finding out my recent pregnancy , then I went and purchased a first response to confirm it

I honestly stuck to first response. We tried for 7 months, and I would just go to the store and buy a box if my period was late. But to track ovulation I bought clear blue tests on amazon.
