I can feel my cup inside me?

I'm 16 and a virgin and tried my cup for the very first time yesterday. It took me an awful lot of courage to insert it fully and let it pop open, I've never used tampons so shoving a cup up my vajayjay was quite a big thing - I was shaking so much!

Anyway once I inserted it, I could feel it quite badly, so I popped a finger in and there was a hissing and it felt a lot better, but I could still feel it inside me. I'm not sure if this is because I'm just not used to things inside me or if it wasn't placed right.

It was quite low down, I could touch the base very easily without having to reach up.

Any advice would be much appreciated x
