Im very sorry, Emelda. Essentially in a 'normal' pregnancy the HCG level should be doubling- tripling every 2-3 days, Im guessing that's why the GP is saying it 'wasn't looking good'.

My first pregnancy was very similar. TTC for 5 years finally got a BFP, HCG at 5- 5.5ish weeks was 160, 4 days later it was still 160. It then started rising but not as fast as it should have been. I eventually required a D&C. I'm not saying that is definately what is happening with you, just that my story is similar

Ring your Dr tomorrow, have a chat and maybe another blood test to confirm what is going on.
