vomitting & nauseous at 12 weeks

#1stimemom 12 weeks 2 days, im a first time mom. Been feeling so unwell since 5 weeks. Vomitting whatever I eat, nauseous all the time and feeling so weak. But at this point im at my lowest. My morning sickness isnt just happening in the morning, it happens at night too before i sleep. i could be a merlion every where i go.Usually at what week does this stop and any tips on what i can do to feel better?#advicepls #pregnancy
