when she said there it is, it's in the right spot - here's the head and here's the rump and I can see the heart beating my eyes just filled with tears and I think I missed half of the rest of what she was saying. she seemed to repeat it all though. first she did the tummy scan and said it looked ok, though was too small to see anything clearly. then I could go to the toilet and then she did the internal scan which was longer. she said my left ovary was enlarged (I think it's pumping out most of the hormones) and right was regular sized. my left side has always been dominant. (the cycle when this bub was from only had follicles on left, none on right) the size being a bit behind sounds like it matches the hcg level from last week.
it keeps progressing from here on in.
