weight gain/loss?

Le
I'm 13 weeks today (yay) and gained about 4 pounds during weeks 5-8, but recently weighed myself and I'm almost back to my pre-pregnancy weight. I haven't had bad
Morning sickness- just occasional nausea and got sick 3x over the 13 weeks. Is this normal? I'm going to see my OB Tuesday, but just wondering. Also, is anyone else super hormonal still?
