So I took a dollar store test yesterday and within the time limit got a positive I’ve taken these tests many many times and a line only came up when I was pregnant for my other 2 babies !!!! That test was taken around 1030/11 so later in the day I took another dollar tree test and came negative so then I bought the Walmart cheapie and it was negative so then I went to dollar general and got the 2 pack blue dye test I took one last night it was negative and I took one this morning and it was also negative idk what to believe 🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️ my period was suppose to come tomorrow
