Sorry for my ignorance but I'm not a regular spa-goer and not sure if it's OK or not. I've had a girly spa date booked in with my best friend for a while now but last week found out I was pg (haven't told anyone except for OH). I'll be 7 weeks when we're due to go to the spa. It will be a hot steam room and plunge pool type affair. Not planning any massages etc. Is it OK to go or should I cry off / try and rearrange to do something else?
