<s>[INST] Hi, Ive had the implanon inserted on the 23/Dec/2013 and this is the first time Ive used contraceptive. I left for a holiday across the country about 5 days after I had it inserted - my diet and eating routines have changed, and have noticed recently that parts of my stool has become bloody (almost a bright red), and Im experiencing no pain. Could this be because of change in biological routine because of my diet or an effect from the implanon? [/INST] Hi, Insertion side effects of implant include local irritation, itching , bruising at the site of insertion. Bleeding in stools is not expected after implant insertion.  - ideal time of insertion is within 5 days of periods. If it is after 5 days post menses, additional protection is needed for one week.  - Implant causes irregular vaginal bleeding which may be mistaken with blood in stools. Please confirm it. Please consult your doctor if you find that blood is in the stools only & not vaginal.  _ blood in stools can be possible with some intestinal infections, piles, fissures.  Thanks </s>
