Is Breastfeeding Not Safe While On Primolut N?

Hi. Im a breastfeeding mum of 7 months old baby. I plan to take Primolut N to get my period come in this certain time. but I read its not recommended for breastfeeding mum. So should I not breast feed while I take primolut n.. but can I continue breastfeed after my period come or after I done taking the pills? Thanks doctor :)
