In the absence of effective access to contraception, more pregnancies are expected to be reported as unintended, a significant proportion of which may be terminated (Abbasi-Shavazi and Hosseini-Chavoshi, 2014). Being young and having a low level of education, poor economic status as well as less access to effective contraception all contribute to higher incidence of unintended pregnancy (Khatiwada and others, 2013). Contraceptive use failure is one of the main direct causes of unintended and accidental pregnancies (Blumenthal, Voedisch and Gemzell-Danielsson, 2011) and can create a demand for abortion. A study of 27 countries indicated contraceptive failure as the most reported reason for prematurely terminated pregnancies (Bankole, Singh and Haas, 1998, Black and others, 2010).
