Quoting Smartass *TTC*:" Not sure. I refuse to shop at walmart. I typically buy the bulk packs on Amazon of HCG strips but ... [snip!] ... on those so I don't like to use them. And with my first pregnancy I never did get a positive on dollar store tests."
You could always just go in there once for a handful of them :p
I think you can have any crazy symptom for pregnancy with all the hormones and what not. Like how I had a sore throat and pretty much as soon as I missed my period I got insomnia... which happened with all three of my pregnancies pretty much immediately. I don't think that's normal. Who knows?
