I'm not pregnant, but I was recently enough to completely commiserate. I am so sorry for everyone's nausea, fatigue, back pain, insomnia, and especially being overdue.
I have two in cloth diapers. I was skeptical at first, but my husband won out with tree hugger rationale. It's totally worth it and most people who have changed my kids agree that it's not a big deal. If you're worried about dealing with them when you're out and about, you can always just use cloth at home and disposables otherwise. (You'll most likely be spending more time at home than you do now anyway.) You'll still save money over all disposables, particularly since cloth diapers hold their value more than I would have expected.
Note to anyone who is early in their pregnancy: being overdue is horrible. For me, it was bad enough to have to be still dealing with third trimester pains, but the ”you haven't had that baby yet?!" over and over drove me crazy. So for the second one, I told all but 3 people that my due date was two weeks later than it actually was. Saved my sanity, highly recommended.
