Hi! So I’m 23. I just found out I’m pregnant literally yesterday. And being the worrier I am I’ve been reading everything I can on plus size pregnancies and I’m freaking myself out. I just ready an article stating all these birth defect being overweight an cause baby. If you’re overweight did you have a safe pregnancy and what can I do to be as healthy and safe as possible now? I’m so scared!
