Bed bugs or something else?

I recently found a spiderweb in the corner of my room behind my bed, with small, oval brown bugs in it. It didn't look like they had heads but they had stripes. They're definitely not fleas. I woke up with three bug bites the other day, but all were in completely different spots on my body and none in a row. I searched every nook and cranny on my bed and mattress and have no sign of any bug in the bed.

Does this sound like bed bugs? Seeing these little bugs seems like too big a coincidence when I woke up with the itchy bites but I assumed they were from a spider since they don't look like bed bug bites. Any advice is greatly appreciated as I'm freaking out over this.
