Help ! 12 weeks pregnant need advice on nutrition!

Hello,

I'm stressing so much these past few days because sver since I've become pregnant, I've been completely off all foods... its my fourth baby but this pregnancy has been super weird to me. My body had been ultra sensitive to anything that contains even the slights bit of oil ! It makes me feel so sick and nauseous I can't handle it. My body reacts even to the smallest amount.

But I have not been eating at all during the day, I will have small bits and prices sometime and when it comes to dinner I never eat everything I have a few bites and the rest im just not interested can not seems to eat anymore.. I used to eat lots !!!. Im terrible with my vitamins too and I beat myself up about it because every morning I say im going to take them And I never eat and feel off all day then night time comes I just want to sleep then I forget the vitamins !

I'm so worried now all these weeks with barely nothing been consumed, that my baby will be serveley harmed by this 😭😭😭😭 im suffering so much being lethargic too.

Someone please tell me my baby will be okay. Ive just realised that its been 12 weeks and I've eaten no nutrition.

Sorry in advance for typos i tend to type really fast lol
