Not bed bugs.

might be squished ant.

I have the same problem, I think that it is ant. Really big problem, I don't know what I need to do with it

Photo?

Definitely not bed bugs. As Jean said, probably a squished ant. Check out the bed bug page of the pest library on my site: www.michepestcontrol.com. The direct link is: www.michepestcontrol.com/bed-bugs. For clarity, here's a decent pic of a bed bug

Photos can be hard to judge, especially if the bug is crushed. Bed bugs are usually flat, oval, reddish-brown, with no wings, but bites alone don’t confirm them. I’d seal the bugs and any nearby bedding in a bag, avoid moving furniture, and check mattress seams, the box spring, and bed-frame cracks with a flashlight. Don’t take unbagged belongings to the new place.

When I dealt with this, a phone consultation helped me figure out what needed inspection before paying for treatment. If you’re in the area, a Milwaukee Bed Bug Exterminator can compare heat and chemical options and explain preparation without automatically telling you to throw furniture away.
