I don't even know if the ferris wheel is ok, it's still a moving ride. I'd stay off everything If I were you
Ferris wheel fine. No tea cups or other moving rides they'll have signs saying no pregnant women
My doctor said no to any kind of amusement park rides. Discuss this with your doctor though, only they can give you the most accurate medical advice for you.
I wouldn't see what's wrong with the Farris wheel or the merry go round. Def nothing that went upside down or real fast lol. Enjoy the time just the three of y'all :)
