Taking classes while pregnant versus after baby

Hey ladies. I'm having a big dilemma about whether to take my classes while I'm still pregant or wait a bit after baby is born. I'm 22 weeks now and I'm worried I'm going to burn myself out going into the third trimester if I have to take a class. BUT I'm just as concerned to wait until after my baby boy is born to do these online courses for work for fear of sleep deprivation and losing precious time with my little one.

Thoughts or anyone have a similar experience?
