Some people start a lot slower than others with their hcg levels. Your having more bloods tomorrow, right? So, by Tuesday you'll hopefully have a clearer picture. Digis aren't the best for dating. If you google info about them you'll see loads of people with similar questions. I'm thinking that if there was a problem when you initially thought then you'd be seeing a not pregnant by now. I'm not saying that everything is fine because no one knows that, but things could well be.
Until you've got a not pregnant, or are bleeding, you are pregnant. Digitals aren't accurate. Some ladies take ages to move from 1-2 weeks. Some randomly don't even though their pregnancy is perfect. Some ladies have slow rising hcg to start. Doubling time is 48-72 hours on average. I personally found pink dye better, though even they can't be used to follow progression as dye levels vary, urine can be more/less dilute etc. I will admit I used these more than digi myself, as they gave a better rough guide.
There are a million reasons why your digi isn't showing 2-3 yet. Yes, miscarriage can be one of them. But there are lots of other reasons as well.
I really, really feel for you Glong. I just want to come and give you a massive hug. Worrying comes naturally, especially after a loss. But this is doing you no good. You're going to make yourself poorly.
It's a lovely day here today. If it is where you are, go out for a family day out with your son and oh. Do fun, nice things. Have a picnic, go the the park, or do something different.
At this moment in time you are pregnant. No one can predict or change what will happen in the future unfortunately, but now you are pregnant. Look after yourself and be kind to yourself xxx
