Update: I went to the Dr. again for another transvaginal ultrasound this time it showed a fetal pole but no heartbeat so I go back yet again this thursday. I am hopeful yet scared!  The measurements said 3.4.mm & 3.6mm Im not sure what that means He said Im about 6 weeks... and I should have seen a heartbeat so he is not too hopeful..... prayers please , thank you all so much!
