I have been a lot more hungry lately but after I eat I always feel sick!! I think my baby maybe squishing down on my stomach which is cause so much discomfort.... I've been so scared lately that I'm doing something to hurt him bc Ive been so on & off sick and extremely uncomfortable no the past 3 weeks no matter what I do & half the time I don't even know what's really wrong!!!!
