i woke up earlier to go to the bsthroom and suddenly felt something dripping down my leg. looked down to see it was blood, i have 1 day till my period still and have never had this happen. i have lower back pain and when i wiped it was more of a dark brown/red/grayish colour if that makes sense, not much blood but was still quite a lot when dripping down my legs. usually before my period I'd break out and start cramping but besides nausea i haven't had any signs either. but i have been super stressed (terminally ill mother and a cheating husband topping the stress list)
