Is this unfair to ask of my husband?

My husband plays in a Sunday afternoon pickup hockey league. Its about 25 mins from our house. So when he goes to his games he is gone typically 2 1/2 - 3 hours. Depending on the time of the games, sometimes he misses bedtime, or sometimes he is just gone for most of the afternoon. He also plays in a Thursday night league (which I have no problem with whatsoever). He is gone Monday - Friday for work, typically anywhere from 10-12 hours while I stay home with our son. I am currently 6 months pregnant and finding myself starting to resent him leaving for 3 hours every Sunday afternoon. I have never felt like this before, I think it’s a mix of the busy toddler, being pregnant and feeling like a lot of the time the burden falls on me. Is it unreasonable to suggest that maybe he switch from the afternoon to another nighttime league, so when we have two kids he is here to help on the weekends? The last thing I want is to be a crazy wife, but just feeling a bit tired/overwhelmed.
