Sorry for TMI but for the last two or three months I've noticed that my periods are largely pretty normal but the brown discharge/cervical mucus lasts a lot longer than usual and is sometimes still there over a week afterwards. I have a smear booked for April but should I try and get seen earlier? I'm concerned and scared to google! It's not like an abnormal amount of discharge, it's standard CM but it's brown. Seems to be like sort of stringy old period blood at first and then later on the CM is tinged brown. It always goes back to normal eventually but it's taking a lot longer than usual. I've had a swab for bv and it was negative. Any ideas advice?
