Yes, they do! I used them with my first son and it worked. Also I have a friend who works in the medical field and they actually use the same tests at the dollar store to determine if your pregnant or not.
yep..and a lot cheaper too! :)
Like magic. That was the test I used to find out I was pregnant during all my pregnancies. I would then go buy first responses just to make sure but the dollar store tests are super accurate.
