Not fitting anymore... 😟😔

I’m 13. I got my period when I was 12, and would normally use pads. I started using tampons as I found them easier.

For the first couple of days of me starting to use tampons they would fit in really easy and I could actually put them in easy, without any troubles.

So it’s a couple of days on and I tried to put in a tampon this morning and I could barely fit it in. I haven’t accidentally left one in, or changed brand. Nothing. It’s just isn’t fitting anymore, and I’m doing everything the way I normally would.

Is this normal?

What should I do?

😬
