**TMI** Would you go to ER

On and off cramping and had brown spotting last week light then today after a week of no spotting I’m having heavier but brown spotting upon wiping ONLY in the evening... dr said to be on pelvic rest and drink water but didn’t need to see me from last weeks but if it got heavy or too much pain go to ER. I have a high pain tolerance but would you go to ER for this kind of blood/amount. All brown...
