Most women are able to use diaphragms and caps. However, there are situations and circumstances where they may not be suitable for you:
- if you have an unusually shaped or positioned cervix (entrance to the womb), or if you cannot reach your cervix
- if you have weakened vaginal muscles (possibly as a result of giving birth) that cannot hold a diaphragm or cap in place
- if you have a sensitivity or an allergy to latex or the chemicals in spermicide
- if you have ever had toxic shock syndrome (a rare but life-threatening bacterial infection)
- if you have repeated urinary tract infections (an infection of the urinary system, such as the urethra, bladder or kidneys)
- if you currently have a vaginal infection (wait until your infection clears before using a diaphragm or cap)
- if you are not comfortable touching your vagina
- If you have a high risk of getting a sexually transmitted infection (STI), for example, if you have multiple sexual partners
Diaphragms and caps can provide only limited protection against STIs. Research shows that some spermicides, which contain the chemical nonoxinal-9, do not protect against STIs and may even increase your risk of getting an STI.
After having a baby
You can use a diaphragm or cap after having a baby but you may need a different size. It is recommended that you wait at least six weeks after giving birth before using a diaphragm or cap.
After a miscarriage or abortion
You can use a diaphragm or cap after a miscarriage or abortion, but you may need a different size.
