I had a natural miscarriage shortly after having my 12 week scan (which showed no heartbeat, sac was 11 weeks, foetus was 7 weeks). After the bleeding from the miscarriage stopped, I then started bleeding again about 6 weeks later. The bleeding is very light but has gone on for nearly 4 weeks. Should I go to my GP or just sit it out. I'm desperate to conceive again. Any advice would be great.
