So I’ve just moved into the city, to a clean apartment that hasn’t had any bed bugs. But the other week I noticed a couple of small bites on my feet. They were itchy, but not out of control (on par with a mosquito bite). I got one more on the other foot. Nothing for the rest of the week, but now this morning I noticed a small bit near my knuckle. They’re all isolated and far apart. I haven’t noticed any bugs or droppings or anything that would indicate I have bed bugs (though I know how hard they are to sport), and I also have those special bed and pillow casings that are supposed to prevent them. My roommate was convinced they weren’t, but I’m worried. Is there anyone out there who can help/is more of an expert on bed bugs?

Many, many thanks.
Thanks guys. These answers are very helpful. I don’t have a wooden bedframe (it’s metal with very few crevices), though I do have a wooden bookshelf and desk. Haven’t seen anything remotely peppery. Here’s to hoping it’s not bed bugs!
