Sprained knee

Samantha
So I was adventurous today and went land sailing. Long story short it tipped and my leg was trapped underneath in a horrible angle. 
My period isnt for another week to week and a half. Of course the doctors wouldn't x-Ray. No meds just an ace bandage mean while I have radiating pain from my toes to my back. Urine test came back negative because it's too soon to test. 
Am I going to hurt anything taking ibprofen? I know not good to take if pregnant. But it's so early.... Would that hurt the chances of conceiving?
