First baby need advise

Selina
 Hi!!! 
​Well I'm 25 weeks &&' 6 days today, now my only concerns are:
​How can I tell I'm feeling Braxton hicks? ?
​What if I don't feel my contractions?!?
​He's very active in the womb will he be a calm baby when he is born?
​I feel like I over eat, baby's tummy measures 1 week or 2 ahead is my constant eating making him fat?!
​He also has an EXTREMELY chunky  face , is this my fault? ?
​Im very scared &&' nervous since I have NO CLUE on what to expect. 
​Also looking for some mommy / mommy to be friends. 
​Thank you all who helps ?
 
​my baby boy Jordon.
