There is a third emergency contraception option that contains a combination of progestin and estrogen. These are the least effective of the three oral methods. We'll go over the subtleties between these two types of emergency contraception later. You do not need a prescription or proof of age to purchase Levonorgestrel options at a drug store. If you don't see it, it may be behind the counter with a pharmacist. Feel free to ask them no matter your gender or age. Other clinics, such as Planned Parenthood or a local family planning clinic may carry it. Some are even available online. With these, it's best to factor in shipping time as well. These are not the only types of emergency contraception, either. The copper IUD, also known as the Paragard, may be used as emergency birth control if inserted within five days of conception. It is also the most effective form of emergency contraception, according to a review of 35 years of study. More specifically, the copper IUDs were 99.9% effective, according to research. That's 10 times more effective than the average emergency contraception pill. Note: A menstrual cup is not a form of birth control, meaning that it is not a diaphragm. These are exclusively reserved for period care and are not designed to prevent pregnancy or STIs. Most experts recommend inserting a copper IUD within five to seven days of unprotected sex. Why would copper be more effective than the morning after pill?
