Hi Mayra. Some additional advice from Ellen regarding tampons in a prior post that may be helpful for you:
“Try tampons on one of your moderate flow days, always use back up of a pad at first and then a panty liner once you are more comfortable with the tampon insertion. Pay close attention to the angle of your insertion… Just like the dilator you need to angle towards your rectum and then in and up. You may also need to try different brands to find the best one for you. Like me for example, I used the same brand for years until I had children then they did not feel comfortable and were not easy to insert. It took several different brands before I found one I could comfortably use. Patience is the key to tampons… It will happen, just don’t force it.”
