Menses

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

With frequent exclusive breastfeeding, lack of menstruation is common (Kramer 2012). The contraceptive method of lactational amenorrhea (LAM) is based on exclusive breastfeeding with frequent feeds (more than 7 a day) spaced at most 4 to 6 hours or without a nightly break and, as long as menstruation does not appear, it has an efficacy of 98% as a contraceptive in the first 6 months postpartum (Sridhar 2017, Berens 2015).

With the onset of menstruation, some mothers may notice greater sensitivity in the breast and nipples.
Other menstrual-related problems have been reported, such as breastfeeding aversion and agitation (BAA) (Yate 2017).

There are slight changes in the composition of the milk for two days, about 6 days before ovulation and for another 2 days about 6 days after ovulation: sodium and chlorine double their concentration and those of lactose and potassium decrease slightly (Naqvi 2001, Hartmann 1982).

Perhaps these changes may affect taste and explain the rejection that some infants may have during those days, although there is very little published literature on this (Lawrence 2016 p332).

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia
