18 just found out that I’m pregnant, we’ve been trying so it was planned. I live with my grandmother, but she’s very religious & gets upset very easily ( honestly terrified of her) but my boyfriend & I are getting our own house soon! So what I need to know is how I should tell her? thank you in advance!

Also I’ve been having cramping.. enough to make me wanna curl up in a ball, it’s sharp & sudden. Happens every now & then & isn’t constant, should I be alarmed?
