Satisfy help me. Repute I have bedbugs.

I just moved into my very first rental house, ever. It's a huge house with a lot of rooms where students live. And I think my room has bedbugs.

Just now as I was searching my brand mattress which still has the plastic on it, I caught a very small, narrow, long bug, yellowy/clear-ish with antennae moving on top of my mattress. It was shocked by the light as I was using my phone flashlight, it tried to get away but I killed it. On my bed there is also something very small and black which looks like a piece of a shell, and some other unusual looking small things lying here and there on the mattress. It's a new mattress, my landlord replaced the last mattress and box spring which I thought looked suspicious. I suspected something was wrong and I've been very paranoid, losing sleep, but he claims that his exterminator recently looked at it to quell my anxieties and the room is 'clear.'

That was a big situation my crazy mother got involved in and she was very aggressive and nasty toward my landlord saying matter of factly that I had bedbugs (before he claimed his exterminator looked at it), leaving him voicemails threatening him and everything. I don't know what to do about this, what to say, or if this could be something else.

I also have three red, but not itchy, pimple like bumps near my pelvis. One of them has a red mark in the middle, like a puncture wound. Also, my room has an unusual smell compared to the other rooms, and I heard that a sweet, kind of bizarre smell can signify bedbugs.

I need help. What does this sound like to you? What would you do in this situation? I can't believe it. Do I talk to my landlord? If so how do I do it without sounding batshit crazy and what do I say? I thought we put this bedbug issue to rest. I'm in a state of shock, my worst nightmare sounds like it came true, in the very first off-campus place I've ever moved into. I feel alone and clueless about this. The semester just started and I just can't be focusing on this
