What if the cervical cap is causing irritation?

The irritation could actually be from an allergy to spermicide.

Try this: If the irritation isn’t too bad, you might want to try another brand of spermicide.

Still not working?

If you’ve tried different types of spermicides and are still having irritation, think about trying a method that doesn’t require any, like the IUD, shot, patch, pill, ring, or implant. If you want to stick with a barrier method, you could try non-spermicidal male condoms.
