Implantation bleeding?

Angel Rogers • 24 years old • Wife [9.9.17] • 2 blighted ovums 8/17/18 & 12/7/18 •TTC our rainbow 🌈 I have PCOS and blood clotting disorder

I got a positive pregnancy test with a FRER 2 days ago, my hcg levels yesterday was 83 and I go back in the morning to make sure it’s doubling. Just a few minutes ago I had a little bit of blood mixed with discharge when I wiped. I am having mild cramps.. could this be baby getting adjusted or MC? I didn’t have this with my last two pregnancies (blighted ovum pregnancies)
