Honestly, mas safe na tanungin mo talaga ang OB mo or pediatrician about Myra E while breastfeeding kasi they know your full history! One of my mum friends asked her doctor din and she was cleared, but it really depends sa bawat mama, better safe than sorry, diba? I've heard maraming moms take it, pero I'd rather you get the go-ahead from your doc first bago mo i-take regularly, especially since baby is still breastfeeding.
