Tmi!! 7 weeks pink when i wipe.

Ive been having light pink only when i wipe. This has been happening on and off the past 2 weeks. I have my appointment tomorrow with the doctor (finally). I'm just wondering if this sort of thing has happened to you girls. My coworker said it happened to her and she has 5 healthy kids. But still that miscarriage worry stays in the back of My mind. 😔 i don't have any cramping just some slight back pain, sore breast, headache, and nausea in the morning. I just wish i wouldn't worry so much. I told my SO whatever happens is in Gods hands and there isn't anything I can do to change it.
