Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research is to determine whether there are differences in ovarian suppression between women who are feeding at the breast compared with women who are pumping. * In the main study, the aim is to compare reproductive health outcomes, including amenorrhea rates, duration of lactation, and resumption of sexual activity, between mothers who are exclusively breastfeeding (i.e. feeding at the breast) and those who are pumping after a term or preterm delivery. * In the sub-study, the aim is to determine the feasibility and acceptability of using urinary luteinizing hormone (LH) detection kits at home to detect ovulation in exclusively breastmilk feeding women.
