Family keeps making plans for water parks and amusement parks I'm 8 months pregnant!! Wtf

Mama
My husband's mother-in-law and family keep making plans to do the most uncomfortable or annoying things this summer. Tomorrow they want me to go to an amusement park, I will be 90° out and I'm now eight months pregnant I can't go on any rides, I don't want to walk around and stand in lines. I don't know why it's that hard to figure out that maybe I don't want to go. It's like they don't consider the fact I'm pregnant in anything! I'm carrying small and don't look 8 months so I think they assume I'm just not pregnant and magically pop out babies without actually being pregnant. It's getting annoying, am I freaking out or do I have a mild point??
