[|Human|] Hi i have gad a positive pregnacy with my 1st go at ivf. Went for my internal scan 6w 6d but sac and baby there but no heartbeat but a 5mm bean, which they say is the size of a 6 week pg. Got to go back in a week for re-scan. Could I have implanted late?? And what s the chances I will here a heartbeat in a weeks time. Thanks littlemiss
[|AI|]  Hello, and I hope I can help you today. The date of conception is known exactly with IVF, as it corresponds with your transfer date. Therefore, there really cannot be a discrepancy in the ultrasound dating with an IVF pregnancy. However, it can be too early to see a heartbeat on a 6-week ultrasound.  Usually, a heartbeat can be seen in 7 weeks, which is why you were recommended to have another one at that time. I hope I was adequately answered your question today and I wish you the best for the rest of the pregnancy,
