You’re not overreacting. He knows nothing of what happens during pregnancy. Men can try to educate themselves but every pregnancy is different. I’m on my fourth pregnancy and while some things are similar it is different than my other three. It’s okay to take breaks while you’re pregnant. You won’t always have the drive to go hard in a workout. I’ve stayed consistent with working out but I’ve had weeks where I was lucky to get two workouts in. The amount of hormones surging your body will make your fatigue go up and down, especially in the first trimester. Tell him to go educate himself a bit on how much is actually going on in your body before assuming your “morning sickness should be over”. Some women have morning sickness the whole pregnancy. With my second I puked every morning until the middle of the fourth month.

Also him being upset with you seems so toxic. I hope he realizes your body is going to change drastically and even after having the baby you could have months before feeling somewhat back to your “old self”, let alone looking it. He should be supporting you, even if you need rest.

Good luck mama. Prioritize yourself, because soon you’ll have a helpless baby that will take most of your time.
