Thanks for your query.
As per your LMP, you should be around 7 weeks.
However, given your PCOS
problem it is normal to have discrepancy between LMP and ultrasound
At 6 weeks pregnancy
, the fetal pole
alongwith heartbeat is generally seen.
Given your history of irregular cycles, your doctor has correctly advised you to wait for another 2 weeks.
Take the medication as advised.
If a repeat scan after two weeks fails to show a fetal pole with heartbeat, then it is best to undergo a termination.
All the best.
