Well, here's an update.

HCG was 1700 on 5/4, up to 2000 on 7/4 and yesterday were 2600. So they're rising too slowly.

The scans didn't show any gestational sac and they were thinking a molar pregnancy or ectopic or missed miscarriage (when everything stays inside) or (small chance) viable. The scan showed various dark blobs in my uterus.

This morning I saw the senior radiology consultant

Now I have only two blobs, which he says are sacs, and the hollow in my uterus is quite big (which explains why my tummy feels very hard). He has discounted ectopic (thank God) and molar and thinks the most likely situation is that the pregnancy has failed but stayed in there and there is still some "material" in there producing HCG. But he does think it strange that they dropped, then rose again.

There's still a small chance of a viable pregnancy, although he thinks that he should see a heartbeat by now. But because my levels are a bit weird, he's still not quite sure. If it's viable, there are two babies in there. Twins - eeep!

He thinks that all the blobs I had were in fact small sacs, so there were originally about 7 in there. The rest of them have disappeared (been absorbed) and the 2 that are there are getting bigger.

Because I'm feeling really well and there's no risk to my health even if the pregnancy has failed, I have to wait for a week and see him again on Wednesday 19th, after having more blood tests that morning. It's possible I may miscarry completely in the meantime. If so, I'm supposed to keep everything in a container and take it in.

Oh, and a molar pregnancy is when 2 sperm fertilise 1 egg and it multiplies rather like a cancer on the placenta. It looks like a bunch of grapes. Symptoms are grossly elevated HCG, increased nausea and vomiting and hypertension.

So we're just waiting. Again!
