35 weeks pregnant with my2nd baby, have had a brown mucus discharge on and off for about 2 weeks now. midwife not concerned but hasn't stopped.

IF u were my pt: I would do a pelvic exam with vaginal cultures to see if u have an infection and gently examine the cervix to see if it is starting to efface and dilate and do an OB ultrasound to check the baby and placenta and amniotic fluid, no reason to take a chance at 35 weeks and i hope your midwife has good readily available md backup and u are delivering at the hospital.
