Take it easy, and try to clear your plate of anything else that can go. Take a lighter load, if possible, because stress affects the baby. Get a comfortable seat, and try to put your feet up, at least during the second half of your pregnancy. Once you hit your third trimester, let your instructor know when your due date is so that they're understanding if you deliver during class (well, not IN class, but you miss class- you know!).
If you get breaks during your lectures, make sure you get up and walk around during them!
And get your SO to give you foot massages when you get home! =)
