I've been pregnant before twice & had successful births with no problems & have not had a miscarriage once ...i am 6 days late for my period as of today..i tested for pregnancy on monday because i had spotted 1 day only about a wk before i tested but the test was negative, the nurse thinks i tested too early & now i am having period cramps but no blood. Is this a sign of miscarriage?or is my period coming?Should i go see a nurse about this?
