No dear m not having morning sickness
I lost weight during my first pregnancy so I would say its normal :) dont worry.
It is normal to lose around 5 pounds after the first trimester. This is mainly because your body becomes familar with the new hormones and fluids that started grpwng rapidly at first. But overtime it begins to learn how to elevate them out. As soon as you reach your 36th week, which is when baby starts packing on fat, those lost pounds will come back fast and rapidly.
Are you experiencing morning sickness?
