Thanks everyone for these supportive comments.
Well, I just got back from the scan and there's some good news and some fairly worrying news.
The good news is that the pregnancy looks good - the fetus looks normal and the heart beat is good.
The concerning thing is the bulge on the scan. I might have forgotten to mention this last time, but our doctor saw a small bulge near the placenta or thereabouts (this was 5.5 weeks). Well, it's still there, and now they're saying that we need to come back in two weeks for another scan to rule out a "partial mole". This is a fairly rare but definitely bad condition, ie it ends the pregnancy.
We were kind of happy, but also seriously worried. The doctors are so neutral.
So, of course I googled "partial mole" and then I learnt the full extent of this problem - not only does it end the pregnancy, but it seems you need to wait a year to try conceiving again (and sometimes have chemotherapy because it's like a cancer). Well, I mean, that sounds .... just terrible.
I hesitated to even put this up here. I have read loads of horror stories already. I mean, I've been through 3.5 years of trying already - what's a year's break? But still ... it just sounds so terrifying.
Trying to stay positive, but basically submerged in fear right now.
Thanks again everyone for the words of support,
WW
