Feeling lonely

I just found out I was pregnant at the beginning of the week - I'm only 4 weeks 3 days. I was so excited when I got my BFP and told my husband, but last night I was home alone and started to freak out - there's so much information and misinformation out there, so much I can't do, and no one except my husband I can talk to about it. When he got home (he was out having beers with some friends), I mentioned I want to tell my sister so I have someone I can talk to besides him and he got annoyed.

I just want to sleep and cry
