If you are getting positive pregnancy tests and are bleeding, ofcourse there is a point to going to the doctors.... "if" it is an etopic, you dont want to leave it.. Better safe than sorry. If its not.. dont u want to know whats going on? Yes, it could be an early misscarriage... it also might not be...? You wont know till u ask your doc to find out whats going on.

Goodluck sweety I hope everything works out xo
