I think a few of the other girls have had clots throught their pg, and gone on to have positive outcomes, so maybe one of them will post in here..

Was all of the blood the dark brown colour, or was there bright red blood as well? As the dark is probably "old" blood and the red more fresh..

I experienced bleeding in my pg at 6 weeks, and again at eight weeks, and sharp lower abdominal pain from weeks 4-10 with Milo. The cause was not determined other than it was 'non-baby' related.

There are a few articles on the main BB site about bleeding in pregnancy, its not uncommon and occurs about 1 in 5 pregnancies.

I have everything crossed that your scan will go well and there nothing wrong.

Good Luck
