swimming

Ma
So as you know swimming is supposed to be good for you especially in the third trimester. But today i was swimming in pur community pool and after abput 30 minutes the lady came to inform us that the pool is closed due to having chemicals used for cleaning. Obviously they had no sign whatsoever and I didn't know about that. Children were also swimming in the pool. Now I'm freaking out. I took a shower right away and scrubbed my skin off!!!! I just don't know if i caused any harm. I texted my dr's office and I'm waiting anxiously for her reply. Has anyone ever gone through this before?
