Positive test but not?

Hi all-not sure how to feel. Not due period for another 5 days but have felt so up and down. Decided to test using non digital Clear Blue test this morning and line came up so quickly as pregnant. Then my husband got home and downed quite a lot of water but digital said not pregnant. More water later and another non digital said not had no line. Could the amount of water i drunk have an impact? Holding off for period now and if not...will then test in another week. Just not sure how to feel!
