The nurse at my school removed me from PE as soon as i informed them of my pregnancy @ 5weeks , i will be 15weeks tomarrow (:
tell them that you are pregnant and hand them a note from the doctor stating that you cant do everything that a nonpregnant girl can do!
Good Luck
You have to let the teacher know, so they can make accomodations
I think you will have to put off taking your gym class until after you deliver...you dont know what kind of pregnancy you will have...but i would think even if its a perfect pregnancy...your not going to be able to complete the class...
