Hypertensive

my highblood pressure rises to 160/100 5weeks after giving birth. I was advised by my ob to have urinalysis to make sure its not Postpartum Preeclamptia. luckily, negative ako sa protein.. I was given maintenance but unfortunately laging tumitibok ulo ko sa Nifedipine. I went to a Cardio to change my meds. He switched it to Losartan.. And it breaks my heart to know that I can no longer do breastfeed because of this.. Sino sainyo nagtetake ng anti hypertensive meds while breastfeeding? pde pa kayang palitan para makapagbreastfeed ako?
