anxiety

found out im pregnant, dont get me wrong i’m so so happy but people asking me why i look sad. It’s my first pregnancy and the fact that i’m so worried and might look sad is that am afraid something is wrong. Anxiety overwhelmed me. This is supposed to be the happy period and why i’m feeling down i don’t know. I want my baby so much but I feel sad and can’t enjoy it properly cause i’m afraid. Does anyone got thought the same any suggestions?
