one step I'm sorry you're going through this. You're right they have to wait until HCG rises - usually if they can't see anything on scan when HCG is 1500-1800 the presumption is that it is ectopic. But in some cases, HCG does go down instead, in which case the pregnancy (whether ectopic or not) may resolve itself and you don't need any further treatment. So don't worry just yet about surgery etc, there is more than one way that this could play out. And even if it is ectopic, some hospitals offer medical treatment, so it does not necessarily mean surgery. I know how hard this is, but I am sure you are in excellent hands at the JR.
Sebs I think your scan result sounds good - the right measurements, and I don't think they usually can measure the speed of the HB at that size (certainly my early location scans around 5 weeks have just noted the presence of a HB but not the speed). Might the sonographer just have asked about the spotting because the computer form asked? Totally understand the self preservation thing.
purple I'm sorry to hear you've had a rough time - I hope you are on the mend and enjoying your lovely little chap.
Trying to get a bit more positive here - in the process of booking acupuncture, and have started exercising ( not much - 25 mins 5 times a week when I can fit it in), but maybe it will help... And if not, maybe I'll be fitter, which might be nice! Strange contraction-y cramps have gone, but still no period. Sure it's coming though, so on the wine.
