<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have been on depo for about a year now and was suppose to get one two weeks ago but didn t for personal reasons and insurancemissed one n got it about two months later. ... but before that I had an iud after the birth of my now 5 yr old... so I haven t had a period for about 5 yrs now... since I didn t get my shot I had brown discharge and now like a mucus discharge and I m wondering if it is normal for this to happen  <response>: Thank you for the question. What you are describing is normal and probably related to a small amount of bleeding from the lining of the uterus. When there is bleeding in small amounts it frequently makes its way out as a brownish discharge. Other causes include:1. Early pregnancy - check a pregnancy test2. Vaginal or cervical infections - an exam and testing recommended3. Bleeding related to intercourse - could be described the same way hope that this helps.
