I would highly recommend Sink Reflections by Marla Cilley:

and also would recommend that the OP sign his wife up for the daily motivational emails that both inspire and outline a highly successful plan for creating a home through the basic concept of BABYSTEPS.

Look for a link to sign her up for the daily “missions and flight plans.” Marla has left nothing unaccounted for. It is a wonderful system based on the Sidetracked Sisters someone mentioned up-thread. I hope that I’m not repeating information mentioned already by a prior poster.
Babystepping is the way a woman must develop the discipline and habits needed to create a beautiful, inviting home and a family life that nutures all of the individuals in the best way possible. It is your wifes job to do this, your life as a couple is out-of-wack because she is not carrying her share of the work. Being pregnant cannot become a day-in, day-out excuse to fail in the housework department. She is not the first woman to be in her situation and it is unacceptable that she use the excuse of her pregancy and energy level to justify lazy behavior. There are countless women who are far sicker when pregnant, caring for little ones that are way more demanding (or twin toddlers, or even children who are ill themselves) who manage to keep a clean and inviting home. The problem is that of bad habits. It will take a long time to reform her bad habits, but Flylady is the very best starting point for anyone to begin. Flylady’s approach does not demand perfection, but just a willingness to work according to a simple plan that in all seriousness, a child could easily do.
On her website and in her emails, Flylady does sell many of the products she recommends to her readership. I have never purchased any, and do just fine without them. Please don’t be put off by this. Marla (the Flylady) has pearls of common-sense wisdom to offer to just the sort of woman your wife is today. Flylady can change attitudes and give hope. Your wife needs practical support, but without help, the years will slip by and you, the husband, will be increasingly unhappy. Flylady is very accepting, Marla’s own story is one of years of undiagnosed depression, she understands what many women go through. Marla recognizes that thousands and thousands of women have undiagnosed ADD/ADHD. This program is about focus and simplification in order to reach realistic goals in babysteps. The perfect antidotes to the relentless, distracted thought patterns that some of us have going on constanly inside our heads. Flylady is a godsend.
If you have ever watched Hoarders, you can see the ultimate result of slovenly, disfunctional behavior and a pathological relationship to one’s home and material possessions. Watch a few episodes of this and both of you will be up and around cleaning in no time!
Start your wife and your family on the Flylady approach. It’s free and the emails are rather entertaining as well. It will gradually restore a desire for order and cleanliness in your wife, and even small progress will be a relief to you and improve your marriage.
Try this first before counseling. Give her six months or so on the Flylady program. You will see a difference if she can be faithful in just small ways. Help her. This is mainly in her mind. Be cheerful and show her that she doesn’t need to move a mountain, jsut put a plate in the dishwasher. And you will save your wife the self-loathing and depression that most women feel when their home is a wreck for we know that ultimately it is our responsibility to create a beautiful home for our family. Convey to your wife your love for her, and your willingness to use the Flylady approach together, and in time things will be so much better. It won’t take long either, faithfulness in small things is key.
