No she isn't. She's 18. It's your sister that's 16.

Maybe it's yet another problematic female in his life.

I was pregnant three times and never felt nauseous or had morning sickness. I also never felt dizzy or faint, bloated, constipated or had mood swings. My only symptoms were extreme fatigue for the 2nd, 3rd, and 4th month, and tender breasts.

Everybody's different. That's just a list of what she COULD experience.
