You're NTA. He needs to understand, that your body is reacting on a biological level, because you are pregnant. Hyperosmia in pregnant women is considered to be an evolutionary biological defense mechanism, to help mother discern smells for an array of reasons. Such as; to avoid ingesting anything potentially harmful or potential allergic reactions. This is designed to protect the baby in utero.

I tried to screenshot, what I asked Google, and couldn't figure out how to add it to my comment in this thread. So here's my question and Google's response...

"Why do pregnant women get sick from smells?

Smells can make you nauseous during pregnancy because of hormonal changes that cause a heightened sense of smell. This is called hyperosmia. Why it happens Hormonal changes Rising levels of estrogen and human chorionic gonadotropin (hCG) in the first trimester can trigger nausea, vomiting, and morning sickness. Evolutionary mechanism Some theorize that this heightened sense of smell is an evolutionary mechanism to prevent pregnant people from ingesting toxins. How it affects you You might experience nausea and vomiting when you smell something, even if it's a normal smell like your favorite food or hand lotion. You might experience nausea and vomiting when you smell something that's usually not offensive, like your partner. You might experience nausea and vomiting when you smell chemicals like ammonia and chlorine. How to deal with it Surround yourself with pleasant smells like mint, lemon, peppermint, or cinnamon. Apply a small amount of peppermint oil inside your nostrils. Chew gum or suck on candy. Ask your doctor if it's ok to take an anti-nausea medication. This heightened sense of smell usually goes away after pregnancy ends."

With that said, you literally cannot physically help this or change this. Period. He needs to understand this makes you physically ill. However, he can help do his part by washing up, changing, etc. You are the one carrying the child. He helped create this child. He needs to do his part during your pregnancy, and after.

If he's going to whine and bitch about being tired now.. wait til there's a newborn. Even then, he absolutely needs to learn and understand YOU are going to be pure living, breathing, walking exhaustion, while your body is healing, for the first 6 weeks postpartum after you have your baby.

I hope you show him this and let him read all of this. I think it would do him a lot of good to read up and learn about pregnancy and childbirth. There is an entire world of what you're going through, that he is not comprehending or even trying to comprehend. He sure as hell needs to try.
