FREAKING OUT!!!!

So recently I moved into a house shared with a couple. my man's friends I don't know them. so I only moved in about a week or 2 ago. I have my son he is 3 over for the weekends. so Friday my man had a warrant and they came to the house picked him up. and they searched the house. nothing in the house was ours just clothes and stuff. so they put a little draw or whatever the fuck in our room for our tv. come to find out they had a fucking crack pipe in OUR ROOM in the draw that they put in our room. now I explained to the officer i didn't know it was in there that everything in the house was our roommates and I just moved in their. that my son just came for the weekend. as soon as that happened i had his dad come pick him up. now I got a message from his dad asking me what happened at the apartment. I'm so scared that his dad won't let me get him anymore or even worst cps is involved. all because of my fucking roomates. I moved out IMMEDIATELY AFTER literally that same day I took all my shit and left. I'm so mad at my boyfriend for not telling me what kind of people they way and now could cost me my son. I'm also 26 weeks pregnant I'm furious because it makes me look irresponsible and I didn't even know. I don't know what to do . I told my son's father what happened and he hasn't answered back all day I tried to call text everything.
