14
What is category 4 of the UKMEC?
Unacceptable risk if contraception is used
15
The Pearl Index estimates failure rates of contraception - what is the formula?
[No. of accidental pregnancies x 1200]/total no. of months of exposure
16
What does LARC stand for?

17
List the main LARC methods used

Sayana press (SC)
Intrauterine device (IUD)
Intrauterine system (IUS)
Implant
18
