We're in very similar positions as I'm at 8 weeks today, but my hcg was 230 yesterday which is very very very low.
I've been monitored since 4 weeks 2 days and my hcg has been creeping up like a snail. I've been told from day one that it's either going to be an inevitable miscarriage or an ectopic so I'm being monitored pretty closely.
My next blood test is on Wednesday too.
I've had a little bit of spotting last week but I've had no pain at all which is good as I'm not in imminent danger of a ruptured ectopic.
I feel for you a lot as the waiting around for results or for something to happen is torture. We also had to cancel a weekend away (only 4 hours drive from home) as I was told I needed to stay relatively close to home and the hospital.
The problem with an ectopic is that they won't see anything on an ultrasound to see if it's located in the uterus or tubes etc until your hcg reaches between 1000-2000, so for me at least it's a waiting game until my hcg levels start dropping and I miscarry or until they see something on an ultrasound, and with my numbers there's pretty much zero chance of it being a viable pregnancy.
I truly feel for you. There's always hope of course as I've read a few stories online about women whose hcg never gets very high and rises very slowly too and they still end up with a healthy baby. These are rare though, but can happen. I think it's something like 15% that don't have the right hcg numbers yet still have a healthy baby.
I think you'll know more when you get your second hcg results and you'll be able to compare the two numbers to see if they doubled in 48 hours, which is the more important bit.
Sorry for the epic post, but I'll keep my fingers crossed for you.
