Is there any side effect in taking ovral l while give breast feeding to the baby who is 1 1/2 yrs?

Here is what the literature says about using them and others during breastfeeding. Small amounts of oral-contraceptive steroids and/or metabolites have been identified in the milk of nursing mothers, and a few adverse effects on the child have been reported, including jaundice and breast enlargement. In addition, combination oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use combination oral contraceptives but to use other forms of contraception until she has completely weaned her child.
There are non hormonal means of birth control other than condoms.
