Help with pregnancy test!?

Perfectly normal--- i just found out im preg, i took three tests and they were all positive, i wanted to keep one for the "baby book" as i did with my son and now they are all negatives. The line disappeared. With my son i took a cheap dollar store test... and it stayed positive however, not all tests are the same and this time i took first response generic brand... Im sorry that your husband doesnt believe you, I would think he would since, miscarrying isnt something to lie about, nor being pregnant....
