So sick, what's wrong here?

Ha
Yesterday evening around 6pm or so I started feeling extremely ill, like I was going to throw up. I help fine all day long until then. 
It continued all night long until about 5:30am when I woke up and threw up for about 10 minutes...il still sick now and it's a new day. I don't know what's wrong?? 
I'm 23w5d and haven't had morning sickness since I was 11-12weeks. Should I be concerned about the baby?
