One sided pain after IUI

I had an <a href="https://glowing.com/glow-fertility-program">IUI</a> on Monday, January 18th. Yesterday and today I have experienced a sharp pain on one side. Sort of like a cramp but nothing like a menstraul cramp. Any ideas what this could be? I know cramping is normal after an <a href="https://glowing.com/glow-fertility-program">IUI</a>, but not one sided cramping. I'm king of stressing that it may be an eptopic pregnancy. Would it be too soon for symptoms of that?
