Belinda - With both pregnancies my GP ordered all the BT`s then sends the results through to my OB, it think most Dr`s like to send you for a BT. Your right a BT will not tell you that bubs is planted in the right spot but it will show your HCG levels but then again I`m not sure how reliable they are as mine at 5 weeks were only 600 my OB said that wasn`t good and that was with a twin pregnancy so I think each woman is diferent as with a twin pregnancy I think they should be double what a singleton is :-k Good luck at your appointment.
