We are so unsure!!!!

Ok we did two of these tests this morning, they both came up the same. We rang our fertility clinic and they said to take it as a positive test, even though the line is faint, but also have advised us to re test again saturday morning coming. The clinic takes it as a positive test but we dont really know what to think. Have we a baby on board or not? We really dont know what to think or what to feel. Think we will be buys a few more tests?!?!?!?!?!
