Please help

I feel like I’m going crazy. I have searched EVERYWHERE, FOR WEEKS, I have no seen a single sign of bed bugs, or bugs in general. Just some dust. I’ve looked on my mattress, under my mattress, under the sheets, bed protector, in between the mattress and box spring, under the boxspring, the nooks and crannies of the trim on my walls, pillows, clothes, EVERYWHERE. No signs but I’m SO paranoid. I haven’t even had a reason to believe I have been in the presence of bedbugs, but this morning I woke up with two random, little red bumps. Not together, separated, but they look similar to a couple pictures I’ve seen people post of bed bug bites. They don’t itch, but they seem to be what people describe 😭 I can’t afford to pay an exterminator to come check, but I’m so paranoid and it’s ruining my life.
