What could these be?

Anybody know what these might be? I have naturally sensitive skin so I am used to having little breakouts but nothing like this. My family is saying it doesn't look like bedbugs. I use free and clear detergent but I don't think that's it. Thinking spider bites but I have not seen a spider here in a long time. The spots are on my right side which isn't the side I normally sleep on. Neither my husband or daughter have any.
