Morning sickness

Fatimah • Cooking baby #3 and #4⏳
I having really bad morning sickness and doctor doesn't want to give me any medication just yet 
But in having hard time  taking my folic acid and pregnant care pills 
I haven't taken them for few weeks and I haven't been on a healthy diet.
I've been eating what I can and voiding a lot of things. 
My question is will this effect my baby? I'm 11 weeks and 5days.
