You need to see your doctor and find out what's going on. In the meantime, don't run over-the-counter or prescription pain meds for your headache more than 2 or 3 days a week. Taking them more often can compound the problem by cause headaches call rebound headache. Truly, see your doctor and find out what's going on so you can take diligence of yourself. Good luck.

Why Does This Happen ?

i would take a pregnancy try-out anyway just to be sure cuz sometimes it take a while till you "feel" pregnant if its not that then i'd run see a doc about the headache and sharp pains on your side
