Dishwashing and pregnancy

So our dishwasher is currently broken and we need to get a new one. We’ve been washing dishes using a sponge by hand and I’m starting to get paranoid that this could be harmful to the unborn baby. Like if I accidentally touch my mouth after washing dishes or something and if the bacteria can be harmful. I make sure to use hot water and also do another wash before using a plate or bowl just to make sure it’s safe.

I don’t know if I’m being super paranoid and overthinking but this is my first time pregnant and im nervous lol
