Congrats FrankieP, our OB has said pretty much the same as above but pointed out it is really important to try and keep your core temp down as best as possible as bub is very temperamental so drinking cold water throughout is essential to keep this lowered and try not to get your heart rate too high, so maybe back off the intensity a little & be careful when you are going up & down in the saddle - best option would be to quietly talk to the instructor before class and ask him for some alternatives, any good instructor will have options and blend these seamlessly into class without anyone knowing the wiser.
His biggest concern wsa sports invovling jolting or fast movements/changes not so much for bub but actually because we are far more prone to injury as ligaments etc loosen so be careful of fast changes on your knees and ankles.
Best options recommended were swimming, walking, cross trainer.
Good Luck
