Some become pregnant, of those some
have abortions, some switch to other methods;
some go to non-use and do not become pregnant,

Cleland9
of 23 DHS surveys including four of the
five countries in Table 4 showed that the injectable
had the highest discontinuation rate among the six
methods examined; it also showed that the
tendency to switch promptly to an alternative
method after discontinuation10 was lowest among
the five sub-Saharan African countries included.
