    3t is "idely no"n that the notion of prolonged pregnancy& defined #edically as 415 or425 "ees gestation& has een hotly deated "ithin the #edical and #id"iferyco##unities for #any decades. ithin this deate& pregnant "o#en$s voices haverarely een heard. /resented here are the results of a 6ualitative study of self7care in

    pregnancy& irth and lactation "ith a non7rando# sa#ple of "o#en in 'ritishColu#ia& Canada. A panel of 28 "o#en "as intervie"ed in the third tri#ester of
