Hi,
Did you have a D and C after your m/c? I had 3 m/cs, but had to have D and Cs after all of them and even then I ahd different experiences re getting af. It could just be your body triyng to get back to normal. Even though you m/c there are still hormones re adjusting etc. Maybe see your doc just to check it out, you could get blood tests done to check for pregnancy as well.
