Brown discharge

Hi mummies & soon to be mummies! I am at week 5 pregnancy and I'm seeing some brown discharge after I wipe… is it normal or it calls for an emergency? Background, I had a miscarriage last year at week 6… afraid that I'll have another miscarriage. I have an appointment tomorrow with the Gynae, hopefully all goes well 🙏 but would like to hear from some of your experiences with this . TYIA🤍
