The main halachically-permitted options would be a diaphragm with spermicide, spermicide on its own (e.g., vaginal contraceptive film), or Phexxi, a new spermicide-like contraceptive. Though spermicide alone or Phexxi have a lower efficacy than a diaphragm with spermicide, that is likely to be of less concern given that you have begun menopause. To learn more about these options, please see here and here and consult with your physician. Then please get back to us with any follow up questions.
