Six weeks and discharge??

Hi everyone. I’m 33 with a six year old daughter. I was very excited for baby #2 and finding out we were successful after many times of trying. Thinking ahead to a vbac has me nervous. And this time around so early at 5-6 weeks I have had pains like cramping and some discharge. The color ranges from dark brown to white. My first appointment is in a week and the doctor said if I don’t have heavy bleeding and severe pain to wait it out. I guess I’m just nervous. I very rarely reach out on forums. I guess I was looking for companionship. Thanks for reading everyone.
