Hi, I would like to know how you go too. I am meant to be 7 weeks 2 days today. My last period was on the 28th of february. I tested positive 4 days before i estimated my period was due, yet today on a dating scan they tell me i am 6 weeks 2 days. The heart beat was 61bpm, then 72, then 132. So im guessing that is what irregular is but she didnt tell me anything which i thought was useless. She just said come back in 2 weeks and we will scan again. I wont be going back. I am going to an OB who speacializes in ultrasounds. He is the best around but you pay a fair bit. I would of just liked her to say ok this is what it might mean and given me a couple of reasons. If i'm facing a miscarriage fair enough its very common but to be told nothing is frustrating. Good luck with your next scan. I''d like to know what your bubs heart beat was.
