Long walks at 33 weeks

So I’m 33 weeks now and my baby’s head is already down where it should be. I’m not sure if that has anything to do with my question but I’ll add it anyway.

It’s finally started to get nice out where I live, plus 20 and above this week and I’d like to start walking home from work rather than catching the bus.

I walked home everyday in the summer before I got pregnant but I’m not sure if it’s safe when pregnant or this far into my pregnancy. It’s about a 1.5 hour walk. I have 2 weeks left till I’m done work and I’d love to be able to save on bus fare and just walk home as my hubby drives me to work everyday. I just don’t want to risk inducing labour. Any thoughts?
