Ok please help!

Started having very light pink when I wiped yesterday. This is 2-4 days before period is due. Very minimal cramping, got a little heavier and redder, but still has a pink twinge. Moderate back pain yesterday, couldn't sleep with how bad the acid reflux was last night and super nauseous today even though there's still bleeding it's mostly "heavier" when I wipe (go to pee). Just sitting around it's very light to slightly heavier spotting. But not enough to fill a whole panty liner, in several hours. Been having bad headaches. What do you think.
