I had a miscarriage just over three weeks ago. I was 13 weeks but the baby stopped growing between 6-7. My body passed the baby naturally at this point and did not need a d&c. 
We were advised to try after the bleeding stopped.. which we have. 
I think I ovulated a week ago, two weeks after the miscarriage. I was only going by CM and pregnancy test confirmed the hormone was out of my system.
Yesterday I had some brown bleeding, and I'm looking for advice on what it is.
I will be due a period in 1-2 weeks but unsure of exact date due to the miscarriage.
I also had a niggly feeling in my pelvic region prior to the spotting. 
Please please I'm looking for any advice on what this could be!
