At 7 weeks I had my bloods done last week, 2 lots 48hours apart. My doctor rung me yesterday with my results that my HCG levels had risen but not quite doubled, she said she's not too worried but because of my history or 4 mc she's booked me in for an early scan tomorrow. I'm so nervous :( has anyone been through the same thing at all?

I'm now 8weeks and took a pregnancy test just now and the line ain't as dark as it was before. Im so worried because when I found out at 4weeks the line was darker than the control line :(
