Morning sickness myths

Hey ladies. I’m about 5 weeks and 3 days pregnant according to how I tracked my ovulation. I’ll get it confirmed at my ultrasound appointment in 2 weeks. So questions....

Of you had morning sickness, what week did that start for you and how often did it occur? Daily? Here and there? Just once? So far I’ve had morning sickness one time at 4 weeks and 5 days. I wasn’t throwing up, but was nauseous with dry heaves.

Secondly, were you pregnant with a boy or girl? Are the myths of morning sickness linking to a girl true? I have absolutely no sickness or nausea when I was pregnant with my son. Not one.

TIA.
