I’m pregnant again...

i’m really looking for some advice or just something to help me through this. i’m 20 years old and have a 1 and a half year old. i’m still living with boyfriend at his parents house. i’ve been a stay at home mom. i’ve been on birth control and was not planning on another pregnancy for awhile til we at least had our own place. but now i’m freaking out that i just found out i am pregnant today on Easter. anyways his parents say that we “aren’t aloud” to have another baby until we move out. and my boyfriend is the kind of person who thinks i’m always doing everything on purpose. and i’m afraid of what his and everyone’s reaction is going to be. if i were to believe in abortion that’s what i would do but i don’t. my mind is going so crazy i can’t even think. how am i supposed to tell them?!?!?
