What if I scratch the surface of my cervix?

Scratching your cervix sounds bad. It should not happen very often and is less likely to happen when you have had practice.
Still not working? If you want to try another barrier method, try one that you do not have to insert, like external condoms (male). Or try a method you do not have to remember every day or every time you have sex, like the IUD, implant, injectable, ring, or patch.
Try a different method: internal condom (female), implant, IUD, external condom (male), Patch, Ring, injectable.
