Teenagers do not know how the contraception works, when they are fertile and the impact of incorrectly or inconsistently using the pill or how to use the condom correctly.
Girls may miss a pill or fail to take their contraceptive pill every day at the same time, as recommended. Some pills are affected by other drugs, such as antibiotics and nullified by sickness or diarrhoea.
The teenager lacks the courage to discuss sex with her parents; she has no money and knows the clinic staff personally, making it almost impossible to access contraceptives.
Clinics are not accessible after school hours, so the teenage girl will be unable to get her contraceptives in time leading to inconsistent usage.
Health professionals at clinics are perceived to be unfriendly and condescending, lecturing the teenager when she approach them for contraceptives.
All contraceptive can fail, although some are more fallible than others. Successful family planning depends on how efficiently the person uses the chosen method of contraception. Half of all unplanned pregnancies occur whilst couples are using some sort of contraception.
