Went it today for my 1st ultrasound! I am 7w6d but my baby is measuring 8w2d! Got to see the heart beat which made me feel so much better! Hearing it wasn't what i expected; it is so small so it was hard to pick up on the ultrasound, but it was definitely there! I will go back in 4 weeks for another ultrasound and hopefully can record that beautiful noise a little more successfully! If you are still waiting for your first visit, i know it seems like it is FOREVER away, but it really comes quicker than you feel like it will! Good luck to all the new mommies to be!
