big hugs to you hun
it does sound like you possibley had a molar pregnancy, because the symptoms you describe at 8 weeks are what happens,
i had my miscarraige in oct, and found out 3 weeks later it was a partial molar pregnancy, in basic terms it means there was too many cells and the placenta overtook the growth of the baby,
it is classed as a tumour, because of the rate of growth but because of the procedure you go through, you get rid of it, however, if it is a molar pregnancy you will be hormone checked for a minimum of 6 months (im on my 4th month now) to make sure its not increasing and the growth isnt back!
this isnt meant to worry you, and if you want any more info please just ask,
this is a horrid time for you and everyone around you. i still get asked now how my pregnancy is going ( being a fat girl) and then the "im so sorry" conversation,
big perscription of tea, chocolate, hugs and wine does help. xxxx
