Hiya,,,, no idea if you can do it on your own but i didn't know the details of a sweep - so i googled it!!
"Membrane sweeping is done by your midwife or doctor. While internally examining you, he or she will simply "sweep" a finger around the neck of your womb (cervix). The aim is to separate the membranes around your baby from your cervix. This releases hormones called prostaglandins, which may kick-start your labour.
A membrane sweep increases the likelihood that labour will start within 48 hours. It has a higher chance of working if the neck of your womb is already softening and preparing for labour. It does not increase the risk of infection to either you or your baby.
A membrane sweep can be uncomfortable as the neck of the womb is often difficult to reach before labour begins and there may be some slight "spotting" of blood and irregular contractions immediately afterwards"
This is what I found! Physically doing it yourself though...................GOOD LUCK!!! doing my own bikini wax is hard!
