March 2018 First baby

I'm about 5 weeks now and I'm a nervous wreck about something happening to my baby. I worried about the first trimester I can't wait until it's over, but new fears arrive. I have no idea what expect. I haven't told my boyfriend yet since we're long distance and I want to tell him in person. I'm honestly scared of everything, but I love my baby so much already I can't imagine finally holding him/her. How can I ease my mind of mommy fears especially so early on? :(
