This product is the 26mm version for women who have been pregnant (even for a very short time) but not had a vaginal delivery of a full-term baby. Designed in the USA by top gynecologists, FemCap is FDA, CE and NHS approved and designed to be lighter, smaller, more comfortable and safer than diaphragms. FemCap is a cervical cap made of medical grade, hypoallergenic silicone rubber that is used in conjunction with a spermicide as a barrier contraceptive (not included). The FemCap comes in a discreet plastic case which resembles a make-up compact to allowing it to be hygienically and conveniently carried. Check out our other Amazon listings for the 22mm version if you’ve never been pregnant or the 30mm version if you have been pregnant and had a vaginal delivery.
