Hi Ratson,
I hope you are fine now...
Rightfully, u will be able to detect baby heartbeat (foetal pole) when u see your bb. Did u see your bb on the ultrasound or just the pregnancy sac? Only when u see your bb, then will the doctor be able to confirmed how many weeks are u now. So, 6.5 wks pregnant is it based on estimation of your LMP?
I had the same situation 3 yrs ago. Unfortunately, by 7.5 wks, there is still no signs of heartbeat, and I have experienced bleeding even though had total bed rest & given Duphaston as medication. Eventually, I did a procedure to remove the unsuccessful pregnancy.
What did your doctor advise you? Perhaps u should seek for a second opinion...
God bless
