Question about morning sickness

Vanessa • Hi! I am a 33 year old mama of 1(born May 2013). We live in Southern California and are excited to be having our 2nd child on March 26th, 2016!!
So I'm just shy of 10 weeks pregnant and I've been throwing up since 3 weeks along, before my positive test. Sometimes I get sick because of nausea, but more often than not, it just suddenly hurts really really bad and vomiting makes it better. I had heartburn in late pregnany with my 1st, but this feels nothing like this. It's stomach that burns and hurts and feels like I'm going to explode. I'm curious if anyone else's morning sickness is similar or if I just have severe indegestion. Tums don't help, but Diclegis mostly does. So confused.
