Obnoxious Neighbors!

Hello all, I'm really at my wit's end this music plays starting at 5 pm and ends not until 2 am sometimes its always the same loud music. Im not sure what I should do, I'm pregnant 1 tri and I have a 3 year old that goes to bed at 7 and the music is sooo loud! What should I do? I really don't want to be THAT neighbor but something's got to give! I need sleep and so does my lo. Should I call the cops? I'm so sick of it. Going over and talking to them isn't an option they only speak Spanish and it's a bunch of men and I won't put myself in that position no matter how nice they are.
