Soooooo ; a while ago I drank some water from a water bottle I had in my car from some time ago ; when I went to take a second drink I discovered it had some plant looking thing growing inside of it 😷 should I be worried? Could it be harmful? I feel a little wierd right now but it could just be normal pregnancy stuff so I don't know what to think ☹️
