Yes, sometime you can feel the tampon inside you.
Why is that? Because it is either
- Not inserted all the way in (a common reason), or
- It was placed a bit sideways, in an angle (not so common a reason)
Can you fix the tampon that is inside you? You can try, but most of the time it is easier to just pull it out and insert a new one instead = make sure to have a spare tampon on hand…
Once a tampon is in position, you should not feel it until it is totally soaked and in need of immediate replacement.
Most women change a tampon sooner than that anyway but, if you are a heavy bleeder, you may experience a ‘full’ tampon on your heavy days. Going swimming may also give the same sensation of ‘fullness’ as the tampon get soaked with water.
On a side note, women with vaginismus may not be comfortable (mentally and/or physically) with tampons, but this is a different issue from routine tampon use.
