Access to a safe abortion already varies depending on what state you live in. Now that the Supreme Court has overturned Roe V. Wade, the landmark Supreme Court decision that's protected abortion rights since 1973, the options will become even more limited – or virtually non-existent – in many states.
There are potential implications for reproductive health well beyond abortion – including types of birth control, fertility treatments and treatments during pregnancy. Many people may have to rethink – or think more intentionally about – decisions they've long taken for granted.
Here's what you need to know about birth control, emergency contraception and terminating a pregnancy.
Consider "layering" contraceptive methods
Different types of birth control have different rates of failure – meaning, contraception does not 100% guarantee that you won't get pregnant if you're having sex. Your choice of birth control might depend on the associated side effects, whether your healthcare provider or local pharmacy keeps it in stock, if you have insurance, what your insurance covers and a method's efficacy.
Once you decide what type of birth control works for you, consider whether you need to take extra precautions if you don't want to get pregnant.
Dr. Katharine White, an associate professor at Boston University's school of medicine and author of the book Your Sexual Health recommends "layering" certain methods: if condoms are your primary method of birth control, consider also using the withdrawal method and/or tracking your ovulation so that you know when you're most fertile.
"I call this the BLT approach because it involves stacking methods on top of each other," like a bacon-lettuce-tomato sandwich. "Together, these can be very highly effective," says Dr. White.
Any birth control, Dr. White says, will be "much more effective than crossing your fingers hoping that you don't get pregnant."
You can keep emergency contraception on hand in case you need it
If your primary birth control fails or if you have unprotected sex and want to prevent pregnancy, you may find yourself at the pharmacy for emergency contraception.
Plan B and other emergency contraceptive pills are not the same as an abortion pill – emergency contraception prevents someone from getting pregnant in the first place.
