Am scarreedd!!! PLz Help!

Hi!!! Am new here. Am 5 weeks pregnant and am sometimes so scared about what'll happen next... Next that is, later during pregnancy, during labor and afterwards. Am aware that am not the first woman to become a mother but i don't know why am so scared. 2 months before being pregnant i was sure that i was ready to be a mom, but now that am really pregnant, am so scared. I keep thinking about so many things: What about my figure? Will it be the same?
