water slides and TTC?

Julie • Pregnant with our rainbow baby! 🤰🏻🌈🥰
We are TTC and we are going on vacation to the dells beginning of May. If we happen to get our BFP at the end of the month; I would only be 4 weeks along when we go to the water park. Is it safe to go on water slides? I know you can't go on roller coasters, but am unsure about water slides.
