4 baby but 1st time sick

This is my 4 baby but it's my first time having morning sickness. I can't hardly finish my food I wake up feeling sick and it comes goes all day. I feel sick if I eat I feel sick if I don't eat 😱😷 
I get horrible headaches that makes the sickness worse which in long run makes the headache worse. Horrible circle lol but I'm so thankful for this baby. ( maybe we will get our girl finally)
