TMI- Discharge; time for a doctors visit?

im 12w2d and On Saturday my husband and I had sex. kinda rough. I noticed the first picture on Sunday and then the second to the past couple days. should I see a doctor or is it normal? its definitely more yellow now than it was Sunday. I had an appointment on Monday where they did a uterine test and every thing came back fine as well as we heard the heartbeat so I don't think I'm miscarrying.
