Possibly, but my wife and I were having a similar issue (not 9 months tho, jfc). Sometimes it helps if SHE makes the first move, and puts in the effort. Also, there was an attraction issue due to a pregnancy. I know it's shallow, but the best thing I ever did was talk to her about it. Now she's a gym rat with a hot body, and her confidence is soaring. We have sex about 3-4 times a week now as opposed to once every other week.
