what's there to do at the spa?

It's my friends birthday and she has invited me to this top class spa so I can feel included since I'm pregnant, but I contacted them and they said they do not have any therapists that specialises in pregnancy massages. I'm thinking if I can't go sauna, in a hot tub or jacuzzi then what's the point in going? 
Apart from the pool, facial, manicure.
What do you think?
It's so hard for me to try have fun being pregnant! ☹️
