morning sickness getting worse?

I'm 14 weeks on Sunday and for the past week or so I've felt like my morning sickness has been getting worse particularly at night. 😫 I've been throwing up whatever is I my stomach right before bed for the past 2 nights. With my first baby I had horrible morning sickness and was throwing up everyday once or twice but this time it started out less intense and seems to be getting worse. Any suggestions or ideas as to why this is happening?
