I have a low cervix which probably helps, even though I have short fingers.
Tips to get beppy out
First of all try not to panic as that will make you tense up.
Get into the bath or shower and squat down.
Bear down with your pelvic muscles and at the same time reach up your vagina with your fingers.
If you don't feel the sponge, don't worry, this will take several goes until you can reach it.
Keep repeating the process of bearing down and reaching up until you can feel the sponge.
Once you can feel it, it's just a matter of time before you push it down far enough with your pelvic muscles to be able to grab it.
Don't worry about Toxic shock syndrome as beppy doesn't contain the chemicals that cause that. So if you need to go to bed, just sleep, and in the morning it will in all likelihood be easier to get out.
If all else fails, Walk in clinic it is.
