I Just Accidentally Mixed Bleach With Harpic Which Caused A

I just accidentally mixed bleach with harpic which caused a horrible smell then I quickly researced what happens and about minute ago I flushed my toilet and got out of there, I currently have my bedroom window open and am getting some fresh air plus I have had a quick drink, i could only smell it for thirty seconds and I have closed the bathroom door but I was wondering if it would be safe to go back in there in a few hours
