I am 5 weeks 4 days today and I did a clear blue digital last Thursday and it said 2-3. I have done 4 since (1 just now) and it is still saying 2-3. It should definitely be saying 3+ by now surely. I am so worried as my HCG wasn't doubling in my last pregnancy and ended in mc (I've had 2) and very concerned that this will be the same. I've got an early scan at the EPU tomorrow and I'm terrified that they won't see anything. Any advice?
