fainting

Hi ladies, 
I'm 11+5 and the feeling faint struggle is real. Normally I close my eyes until the feeling disappears but last night while out in public I fainted. I didn't hit the floor hard because my partner and his dad were able to guide me down!! 
My question is is this relatively norma or something I should get checked out?
