"Morning sickness"

So with my first 2 pregnancies (both girls) I was SUPER SICK! Like I lost over 30lbs with each pregnancy I puked from before I knew I was pregnant till after I delivered both babies! With this baby Im 9 weeks & have only got sick once which was this morning & was just a little that's the only time I've even got nauseous so could this be my boy I've been waiting for????
