Anyone else experiencing early heartburn

Lisa • Married 5 years to a wonderful man. Son born 26 Jan 15. Expecting another boy in Nov 16 X
I'm 15 weeks , never had heartburn in my life and the past 3 days I have had it all day, so bad yesterday it caused me to throw up.
​I understand this isn't normal so early in pregnancy but just wondering if there is anyone also suffering?
​Thanks
