I am having severe pain in my head eyes and left ear should I be seen

Make an appointment. Going to an ER just isn't as good as getting a more thorough checkup, since this sort of pain can be hard to diagnose.
Call your DENTIST too! You'd be surprised how many MDs say they can't find anything wrong with pain in the face/head, send you home with painkillers, and never refer you to a dentist.

Hi! I started my period on December 17 and it lasts for 4 days. I stopped bleeding for seven days. I had unprotected sex December 23 and 24th. I took plan B on December 24th. All of a sudden I am starting to bleed heavily. It started in the evening of today. My ovulation starts December 31. Is this abnormal?
