Positive test, no symptoms, pregnant?

Jenn
I have only been off birth control for two months now. That being said, my flow is really irregular last month so not sure when it should pop up this month. I took a test on Sunday and got a very faint positive. Went and got two more different tests, took one and got a faint positive. Waited till Tuesday and got a stronger positive. My lower abdomen has been cramping like my flow is coming, but no flow. I do not have any pregnancy symptoms. Not nauseous, boobs don't hurt, no intense smelling advancement....lol. I want to be pregnant! I'm just not convinced. Should I be showing signs at this point? Should I take another test? Should I be concerned for a miscarriage?
