Brown discharge x1 week

Michele

Has anyone had this type of discharge for a week and everything be okay? I have bicornuate uterus and have had this discharge for 7 days. I had blood work on 11th and hcg was 4348. Then 13th hcg was 8037 and progesterone was 8. Dr put me in progesterone and did an ultrasound and stated that my sac was measuring at 5weeks. It was almost 8mm. Sac was empty and go for another ultrasound Tuesday. Put I’m still having this weird discharge.
