PLS HELP: pregnancy

Ok so my bestfriend is pregnant and she's about 1 month pregnant , she's about to turn 18 in a few months and she's really scared to tell her mom cus she's afraid that her mom will kick her out the house even though I told her if that happens she can come live with me. She wants to keep the baby too . Any ways she can tell her mom she's pregnant ? Btw her moms a little crazy 😳
