Help a sister out

Claire

So I’m going on a beach vacation this summer. I have one more period before I go and I need to be able to be mildly comfortable with tampons because I’ll most likely be on my period there. Putting In it’s fine, (I’ve used them twice) but pulling it out dear mother of god I nearly screamed. I realize it was probably not the right absorbency, but I would love some more tips. (Also how do you know when it’s full? How do you tell?)
