Brown watery discharge


I’m pregnant about 4 weeks and I’ve been having brown watery discharge since I found out on Friday. I took a test last night and the lines were darker than they were when I tested Friday. It sometimes is light brown and sometimes dark. No red no pink. I’m just worried I hope I’m not miscarrying. I’m not having any cramping at all and don’t have an appt until next Tuesday. I’m really scared. 😭
