When you see your Dr hun ask if you can have an u/s as you have been concerned. It will help ease your mind. Yay for the ms returning, the flu is also a common pgcy symptom. They may not be able to hear your bubs HB until almost 14wks, also depends on the DR trying. Which is a reason for getting you to ask for an early u/s. Lots of sticky vibes coming your way. hugs
