Big relief!

My little bean's heart was even beating - 98 bpm! Physician assistant said that if I were 6 weeks pregnant, they would expect to see a HB of 100-120. If I implanted late and were only 5 weeks pregnant, 98 bpm would be fine.
Doc initially thought I implanted late because my HCG levels started off really low so I am hopeful.
Technician doing the U/S thought the yolk sac looked large. My doctor's office did not have that info and could not comment so all I can do now is wait and see - next U/S is next Monday
