Should I be suspicious?

What would you do if you found 3 feminine douches in the cabinet of your room and no one in the house knows who it’s for or where it came from? My husband and I are currently staying with his parents and younger brother while we shop around for a house, my brother in laws gf also spends the night sometimes; but none of us females use feminine douche, None of the males know who it’s for either. But what gets me is why is it in my room when I was in this cabinet a week ago and they weren’t there.

Edit to add- I wouldn’t care if I would’ve found it anywhere else but a cabinet in my bedroom. Which is why I started asking people who it was for as I haven’t used feminine douche in 13 years

Edit to add- I don’t think it’s a hint towards anything as all the females in the house agree that douching just makes you worse down there and not actually makes you cleaner. My mother in laws is big into keeping to that because when I asked my brother in law’s gf about it she overheard and got ready to start giving a lecture on all the cons but we all agreed that none of us would use douche or support any of the other using it. So that’s why I’m kind of suspicious of my husband
