Headaches: Since you've missed your period, pregnancy must be considered and if pregnant, ok for any medications should be obtained from your obstetrician. The headaches occurring for 3 weeks may be related to sinus congestion but other causes must be ruled out. A neurologist is best qualified to evaluate you. Get a pregnancy test before any xrays or medications are recommended.
