Got my bfp yesterday 1st cycle after mmc. This morning I started spotting, I had sharp pain all day yesterday so I've put it down to implantation. I've got no cramps, it's more like a discharge. It's brown/pink. I've done another pregnancy test but it was a 1st response rapid response amd the other one was a frer, which is why there might be no progression. However, I've done a cheap ic strip and it's stronger then what if was yesterday. Could this be implantation bleeding or could I be having a chemical?
