Hey hun, the only thing that's going to help you here is follow up hcg tests. I think this is why many places won't scan till 7 weeks. I pushed my NHS hospital and called 2 private hospitals and the NHS just refused and the private clinics told me that yes they would scan me if I wanted but more often than not that before 7 weeks a scan would be inconclusive and just leave me more confused.
Another hcg should indicate if you are doubling up (good), falling (bad) or hovering (also bad, as it can indicate ectopic). I hope you are ok, I really do.
If you want to talk PM me, as I started to m/c at 5 weeks just 4 weeks ago and just finished the whole hcg blood process on Tuesday.
Oh Porkpie - hope ur doing ok, its still v early in ur preg and monitoring ur hormone level is the way to go. When I was up at the Ulster last week I was 5 weeks, 5 days and they said a scan would be no use at showing anything till at least 6 weeks maybe even 7. I so hope ur levels double for u.
I think ur gonna need daily morning sickness, heartburn, extreme tiredness, a massive swell to the chest, some dizzyness and major cravings to convience urself this LO is really on the way - so roll on the preg symptoms for u (in a good way cos I don't really want u to suffer with all that)
Hope the next few days brings good news and ur hormone levels rocket.
