Although it turns out there was a very sweet reason why he took the photo.
"My husband kindly snapped this photo of us earlier this week - I asked him not so kindly to f—k off and he did," she wrote in the Instagram post.
"When I walked out of the bathroom an hour later, I asked him why he felt the need to capture that exact moment, since it definitely wouldn't be one I wanted to remember."
Upon hearing this her husband smiled and said the following (very sweet) reason why he took the picture.
"Well, you've been sick all day every day for the past four weeks, you keep asking me and yourself if it's even worth it," he explained.
"Having to feel this bad, so I wanted to remind you of why you're doing this," he continued. "Because even though this part sucks, it will bring you something so extraordinary in the end - it will bring you someone who loves you unconditionally even on your worst day."
Wilson's husband continued: "It will bring you a person that doesn't care about the fact that you haven't showered in four days and you're puking endlessly, she will still want to be right next to you, she will hold your hair up, pet you on your back and keep telling you that you're doing great, that my dear is the purest kind of love I've ever seen".
Hearing this sweet sentiment, she thanked her husband for helping her see "the bigger picture".
"If this baby turns out to be even 1/10 as amazing as our others did, it's worth every single second of it," she said adding, "Even though this part truly [does] suck."
Instagram followers loved the message from Wilson's husband, offering their own support to the pregnant mum.
"Such a sweet message, hang in there mum," said one user.
"I'm crying. This is so sweet."
"He's so right," agreed another. "But I really hope that you get better soon and will be able to enjoy this wonder."
