Worked in the er and we used the cheap ones lol, we do so many. Everyone thought we did something special, they're testing the same thing. Don't waste your money the dollar store and Walmart ones are perfect!

Number on the box***

There’s a possibility you haven’t used enough urine, although I think that’s unlikely because you’re supposed to do it under a direct stream AKA when you have to go to the bathroom. I’d Call the number and get your money back.

No control line means the product is a defect. 🤷🏻‍♀️ think you just wasted your money babe.

Also, wait 4-6 days after missed period and use a first morning sample before you’ve drank any liquids.

Should work.

**Do not buy cheap brands at Walmart.** Go to the pharmacy where you know they keep up on expiration dates of all their health products.

Maybe not enough urine mine does this to

The 88 cent ones at Walmart are great quality by the way

@zoeysmom28, is your urine extremely diluted or something? Idk why they would all fail to even show a control line. So strange

I’ve tried other brands too, they all do the same from this particular Walmart obviously. I bought 3 really expensive ones && they didn’t change at all. Now the cheap ones don’t change either

I’ve never used that kind but do they have some type of money back guarantee? If the control line isn’t even showing then it’s defective
