from experience. if u happen to have bleeding with back and abdominal pain like period cramps then i suggest u visit the emergency room immediately. but if its just brown discharge without any pain then i wouldn't be worried too much as it might be just implantation. but if u feel unsure and concern do go see a doctor. u can take a picture of it to help ur doctor understand more and tell them what u feel. the more info can give the more they could understand and help u.i hope this info helps😊
