Rides at Universal?

Hello all! Hope everyone is well. At the end of the month we’re going to celebrate our sons 8th birthday at Universal, some family will be there. My boyfriend doesn’t want any family to know I’m pregnant until 12 weeks. I’m not sure if I can go on the rides, and my sister is coming from New York to visit. I suspect she will know if I’m not going on any of the rides? Obviously the health of the pregnancy is extremely important to us and I would not want to jeopardize anything. Personally, I am NOT a roller coaster person and don’t ride them! My son loves the animatronic rides like Spider-Man and transformers (if anyone is familiar with rides there). I want to be there for him too on his big day.. Are those at least ok to ride? If it’s not ok, what excuse would you guys family as to why you’re not riding them?! Lol. Thanks guys!
