Morning sickness gone too soon?

This is my second pregnancy. For first pregnancy, my morning sickness lasted till 2nd tri. On my current pregnancy, my morning sickness lasted about 5 days only (but those 5 days were very extreme, I vomited from day to night and night to day, up to 10 times within 24hrs). Is this a cause for concern? No cramps, no bleeding at the moment, nipples still alittle sore. Did any mummies experience such a miracle of having such a short morning sickness and still managed to have your pregnancy proceed along with a healthy baby? I’m a nervous wreck now. The last we went to gynae, I was supposedly only 5weeks, and had the diamond shape ultrasound picture which was normal. Am due to see gynae again in 2 weeks’ time to check for heartbeat.
