malteser - please wait until you are absolutely certain in your own mind that you have m/c'd. I was not certain and at 8 weeks 2 days went for a scan - report says "measuring 6 weeks - inevitable pregnancy failure", I went for another scan 2 days later - sorry does not look good I was told. Went for another scan two days later again at 8 weeks 6 days - and there is the baby with heart beating!!!!
I have a tilted uterus so my scans all look about 2 weeks behind where they should be.
I am not telling you this to give you false hope, but that if you know in your own mind that it is all over, then you are probrably right. But if you like me have doubts, then wait, don't take the tablets yet. You may well miscarry naturally anyway (I had 6 miscarriages prior to this, so I know it is not easy). But if nothing has happened in a couple of weeks then you can request another scan, and by then you might be more able emotionally to cope with taking the tablets.
I hope this does not raise false hope with you, but I am really saying, trust your own instincts, with my previous miscarriages I "knew" before the scans were even done that I had a failing pregnancy, and sure enough went on to loose the pregnancy within a short time. But this time I felt it right to not give up hope, so trust your own instincts. And wait until you are ready before taking the tablets.
I will be thinking of you.
