I had an early scan on monday and a heartbeat was detected along with yolk sac and was dated between 5 & 6 wks. All last night I was feeling really poorly and when I got up this morning I noticed some brown discharge in my knickers and when wiping. I now have lower back pain and am obviously very worried. I have seen the dr and he said it is threatened at this stage as im not losing fresh blood but if I do then I am to go to hospital strait away. It seems so cruel after seeing that little heartbeat :(
