6 weeks pregnant - can I

This may be a dumb question to some but I forgot to ask my doctor. I know hot tubs are a pretty big no no for us pregnant ladies, and I do not wanna put my baby at risk or anything, but at 6 weeks, is it that big of a deal if I go into a hot tub for short periods of time? I know some people who have done a lot worse. Not saying that makes it ok or not, just genuinely curious and curious to see what others think. Please refrain from attacking me or calling me a bad mom, I feel this is a legit question especially since being pregnant is new.
