TMI Anyone know what this is?

I was feeling my body under the covers last night (like always in case I feel weird lumps or scratches) and I found this bump on my stomach that’s near my bellybutton (about 3 or 4 inches from it). Well when I first felt it I thought it was a just a pimple so I squeezed it and nothing. I left it alone and it’s still there this morning. It doesn’t itch, it doesn’t hurt unless I aggravate it by trying to pop it, and I’m not sure what it could be. It’s also right on top of one of my stretch marks.
