Most women experience a temporary loss of libido at various times of their lives, and this is perfectly normal. Stress and fatigue are well known libido dampeners but sex drive is governed by both life style factors and sex hormones. Both men and women have levels of all three major hormones (oestrogen, testosterone and progesterone) and as always with nature it is about balance so to encourage hormonal balance (and a healthy libido) the first step is to make sure that you eat healthily and exercise regularly.
