struggling a bit with this pregnancy

samantha2k15

Before my 12weeks I use to feel sick all the time but was rarely sick that I couldn't eat . Now am 15weeks+ and i am still feeling sick sometimes even retching but nothing comes up because of all this i am still struggling to eat sometime i might be able to eat breakfast but thats me for rest of day which is not helping my stomach pains any suggestions on what I can do until this sickness settles? I have tried things like salted crackers, things with ginger and even tried soup (both tin and honemade)for dinner but nothing works as still feel very sick .
also are migraines normal all time in second trimester? I have hard time telling if my migraines are pregnancy related or because of my epilepsy as i often get migraines when I have my seizures ( I have at least 7 seizures In a week)
this is my second pregnancy with my first (my son who will be 8 this august) I only had sickness upto the 12weeks and didn't have any seizures until the end of the pregnancy. Can anyone help plz. I don't see my midwife for another week or 2
