My doctor told me you wouldn't be able to hear the heart beat on the doppler until 12 weeks and your only 5 weeks so your barely pregnant i agree with the other girls it's most likey just to early wait untill 9 weeks and they should be able to see it on an ultrasound hope everything turns out to be ok for you and your baby good luck with it all
I wouldn't worry unless your hcg level drop as well. Good luck with everything! Try to stay positive and calm. I've been there so I know how you feel.
Sounds a bit early for a heartbeat. I wouldn't worry too much yet. Your hcg levels are normal.
5 weeks may be too early to locate a heartbeat. At this point you'll see just the sac where the baby is growing but not too much definition. I suggest you wait maybe 2 or 3 more weeks to repeat the scan for the heartbeat.
