Many women with hectic and unstable lives may have limited contact or trust with health professionals and struggle with many types of contraception. There needs to be more education and awareness about semi-permanent types of contraception, and these should be given on the spot, instead of needing two appointments as you often do to get a coil or implant. There should also be free morning after pills on demand at every pharmacy. These measures alone would prevent many unplanned pregnancies.
I worked for 2.5 years on the government sexual health and teen pregnancy strategy
One of the key pillars of this was promotion of LARCs in addition to condom usage
The issue with contraception is the gap between perfect and typical use
Combined and mini pill when used correctly are more than 99% effective. However typical use is around 91% because lots of women don't take it exactly when they should
Depot jab is more than 99% effective with perfect use. Typical use is around 91% because people don't always go back to get it redone when it's due
Other LARCs have minimal difference between perfect and typical use because there's limited margin for user error
IUD (copper) and IUS (mirena) are more than 99% effective.
The implant is more than 99% effective
Typical use is about the same because they last for so long
Condoms are 98% effective with perfect use but failure rate is actually very high - typical use is actually only 82% effective
The increasing use of the implant was a significant driver of the reduced teen pregnancy rate (amongst many other factors)
I'm sure there are poster who will pile in and say how they got pregnant on the coil / implant, but the fact is that at a population level, fewer than one woman in 100 will get pregnant on these forms of contraception. When doubled up with condom usage the chances are miniscule.
However failure rates do happen - and the system needs to acknowledge it. But it also needs to be acknowledged that many contraceptive failures are due to user error. Therefore I entirely agree that making LARCs and emergency contraception free and much more easily accessible is absolutely critical
