The vaginal ultrasound is like a vibrator. Hahahaha !! The long ones that's shape like a penis. They'll put some KY on there and put it in there then they'll have to move it left and right, up and down until they can see the heartbeat. Just relax and it will be done pretty quickly. Try to look at the monitor while the doctor do it and you'll be able to see your BB and you'll not feel uncomfortable. add oil !!
Littleponypony : you have OHSS, thats why your 腰圍由25寸變至31寸. My baby also a IVF baby, and i have OHSS, my 腰圍由25寸變至35寸. But no worry, OHSS will start to reduce around week 12. However if you have OHSS, Dr should give you Cardiprin or Heparin. You do your IVF at C+ or Government ?
