bleeding after sex

heather

i’m 7w3d and last night me and my fiancé had sex and i went to the bathroom about 30 minutes later and there was pinkish brown blood mixed with mucus and it was very light but i woke up this morning and it was still happening. i go to doctor to meet my c.n.m tomorrow and to do blood work and stuff. is the bleeding something i should be worried about or is it just a normal thing?

update: i miscarried at about 4:30 10/18/18
