My baby seems fussy while nursing and I just recently started birth control, could the pill be affecting my milk?

If your baby is unsettled while nursing your milk supply may be diminished. The hormones in birth control pills can reduce milk production, especially pills containing only estrogen. It is best to use a hormone free form of birth control while breastfeeding. If you must use pills, the progestin only pill is better because it only rarely reduces milk supply. It is also recommended to wait at least 6 weeks before starting the pill to insure that your milk supply is established and that your baby is growing well.
