Am I really possessed by a demons?

I asked earlier what I should do about a certain problem I have. Well, I told my mother that I had ual with her husband on more than one occasion and that I may be pregnant with his baby. She started crying and shouting and locked herself in the bathroom. She is like a really crazy evangelical Christian so she started praying really loud and saying stuff like "OH HEAVENLY FATHER PLEASE RID MY DAUGHTER OF THE EVIL DEMONS THAT RESIDE INSIDE HER AND THE HELL SPAWN THAT SHE IS CARRYING" and that really freaked me out because I have never seen my mother get THAT crazy before. So I left the house and went to the mall with my friends and when I returned home at like 2am, like half of the people that goes to her crazy church was there. So as I got closer to the front door I could hear them inside chanting in tongues and when I opened the door they all looked at me and my mom's crazy preacher approached me and put his hand on my head and then he said he could feel the presence of demons inside me. He said there are several of them. Am I really possessed by demons or is that preacher and everyone else in my mom's church nuts?
