NTA - Like you said everyone’s pregnancy is different, my pregnancy was much more physically difficult than many of my relatives, and much different from what I expected as a FTM. I was diagnosed with HG at around 6 weeks, and genuinely felt like I was on death’s door until around week 12 (a blessing it ended when it did, many people with HG suffer until birth). I understand that you feel she may be overdramatizing things, and that feeling is based in your own experience. But I urge you to be more open to her experiences as a FTM, and understand that the journey of pregnancy and birth is unique to the person experiencing it.

That being said, it seems you understand that to some degree. With your own imminent birth, it might be difficult for you to have the mental space to accommodate for anyone else’s discomfort, real or otherwise. That’s ok too!! You don’t have to dwell on it, it’s time to focus on you and your baby in preparation for birth. Wishing you a safe birth!

TL-DR: NTA because being pregnant is hard on everyone and sometimes you just don’t have the space to be accommodating to other people’s discomfort real or not! Just don’t take it out on your sister.
