Brown Stringy Discharge Is That Bad??

Terri

I just went in the bathroom.. and when i wiped i noticed some brownish stringy stuff came out of me. I have no clue what it is. I'm not sure if it's something bad. I'm 12 weeks. I just went to the doctor tuesday and everything was fine. Then this.... Anybody know what it is?? I didn't wanna use the real pic so i looked up something similar. I looked it up but didn't help much.
