Cheap 88 cent wal mart test!

Just for the record my period is due 1/14 however I have got a positive every test except the cheap one! First response is so worth your money to anyone wanting to really know if they are pregnant!! I keep hearing everyone say that the cheap ones are the same but I've take a few all negative as far as I can see! Save your money and get a test worth having!! Good luck and baby dust! Thank you to everyone who supported me and helped me read the tests! Last picture top cheap one is tonight other is yesterday all first response were yesterday and today and clear blue was today
