Any mommy's feel like this?

Sammy • Soon to be 21, been a mother to my little man since age 16. I am engaged to the love of my life/highschool sweetheart & we have our miracle girl on the way! Due St. Patrick's Day!
I am having horrible nausea. Up until this last week I didnt have any symptoms but a missed period, a positive test, then pink spotting. I am so sensitive to everything I put into my mouth. I constantly feel sick! The car rides make it alot worse! I didn't have it this badly with my first 5 years ago. Any suggestions to help the nausea? I'm constantly on edge... I need some support!!!
