I'm 6 weeks 3 days and have had light brown discharge for the past couple days. Today when I wiped there was some light pink and it's made me nervous. I've had light, intermittent cramps and light back pain for the past two weeks. Should I make a doctor's appointment? I've seen multiple posts saying it's ok as long as it isn't red, but I'm still nervous, especially due to cramping. I don't have my first visit for another 2.5 weeks.
