Hey butterfly, I suggest take the preggy test and if it is , no medicine...If it is negative, take the medicine - if you really want to know for sure, have your doc take a blood test.
I was using every precaution when I cleaned my kitties litter, (usually my husband does it, but if he's working and it's stinky - i'm not waiting - but I was wearing gloves, mask, etc... After I took the preg test and it was neg (mind you I still having got my period yet - 7 days late now)...I am not wearing gloves but am still covering my mouth (just in case).
But either way, baby dust to you!!!
