I do not think you are pregnant. However, if you have had sexual intercourse after the miscarriage
it is still possible that you could be pregnant again. But the chances are very less.
This kind of spotting is bound to happen after a miscarriage, it is normal. You will soon get your normal periods. If you still do not get a regular period in ten days time, then please get an ultrasound
scan of the pelvis to look for any retained products of conception.
Hope this helps you.
Get well soon.
