help a first time mum out

My symptoms started mildly around week 7 but it got worse from week 10 onwards. I had severe vomiting. Food and drinks consumption and sudden change of smell would trigger my vomiting. I felt lazy to eat because I was afraid to vomit again but I was constantly hungry and weak. It was a dilemma, especially when I was craving all kinds of food but they all ended up in the toilet bowl hours later. This continued til the end of my first trimester, with mild symptoms 1-2weeks into my second trimester before it stopped.
