Is it normal?

So i recently started tampons like 2 months ago and i can totally feel it up there and sometimes its hella uncomfortable walking around with it. It honestly feels like its going to pop out any second. I push it in further to see if thats the problem but that doesnt really do anything. I have to smallest tampon size and im NOT a heavy bleeder either so its not thick, i dont think that going bigger would help at all. I always end up taking it out and using pads for most of time but is it normal to feel your tampon about to pop/slip out or an uncomfortable feeling? My boyfriend says its because im not use to it yet but i dont think thats the problem.
