Thank you heaps Tara I did a little research but couldnt find much on it and as it was of no threat at the time I didn't think about it. I had one that was abt 2cm long at 5wks but was away from the bubs up above the implantation site they said it was 50/50 if it would stick. It's still scarey how much they bleed from such a tiny little thing having a 30-40mm one must have scared the tar out of you. I can see why you bleed for so long in your periods if the whole thing sheds if you can get such a scare from a 2mm x 1mm one lol
