Migraine, fever, while breastfeeding.

Hey, My name is Shibani Manohar, 36F, mother of 4month old, who is currently breastfeeding. I have a history of epilepsy since childhood and I am on medications for it, taking levigress 500 (1-0-1). I got terrible headache / migraine 2 days ago and took vasograin containing ergotamine tartrate and caffeine tablets (1mg+100mg) one on june 1st night, then june 2nd night and today morning june 3rd. I also felt feverish due to overexhaustion yesterday and took a crocin 650 yesterday night (june 2nd) and today morning. Later I checked on the net that vasograin is unsafe during breastfeeding, but I have already fed him after taking the tablet. What measures can I take now to keep my baby safe? Also I feel I am having pain in my throat. What medication can be suggested for migraine and fever for a breastfeeding mother? Please help.
