Is this normal? been on the pill for like 2-3 years now and for about 1 and a half months, ive been having brown discharge/spotting. Im guessing this is breakthrough bleeding. I usually skip my break week everytime which might be the cause but ive never really had an issue in the past. Im just worried if its normal to last this long? the odor kinda smells metallic, like a period.

Theres never usually blood, kinda just looks like dark discharge or maybe old blood if anything

Normal
