Is this from the bug spray or my period?

okay ive been on my period for the past couple days, and sometimes i get general headaches from them but not that often. i sprayed a bunch of bug spray in my bathroom last night, and my head started hurting because the smell was a little overpowering. i didnt directly inhale/ingest it or apply it to my skin though, i just smelled it. now, thirteen hours later, i still have the same headache. could that really happen from smelling bug spray or is it my period?
