I am about 5 weeks pregnant.
I believe the heart begins beating around the 5th-6th week.
I wouldn't worry too much.
I didn't hear my son's hb til week 7 or so and the dr said it's completely normal.
He said normal would be between 6 and 8 weeks.
So you're still okay!

I had a similar experience at the beginning of my pregnancy (I'm now 38 weeks pregnant!)
