Should I go in ??

So I had sex Sunday, spotting when I wiped after sex and then nothing all Monday until I woke up Tuesday and there was blood. It started super light but Tues afternoon it got a little heavier and has stayed that was since. It's been 3 days and it hasn't slowed down. My period is supposed to come in a 8 days but it's always on schedule and this isn't that heavy of bleeding. I have been trying to get into a gynecologist to get check just to be safe since Tuesday but there's a bunch of hoops to jump through. Should I go in somewhere else if I can't get in to the gynecologist tomorrow?
