Ahhh 7 minggu, memang lagi heavy period untuk morning sickness kan... a few of my mum friends swear by eating small frequent meals, even just crackers or toast before you get out of bed, so perut tak kosong sangat pagi-pagi. Ginger tea or even just sniffing lemon helps some of us too, plus make sure you're drinking enough water throughout the day sebab dehydration makes it worse. Rest as much as you can lah, your body is working hard right now, so jangan push yourself. If it's getting really bad sampai you can't keep anything down at all, do mention it to your doctor just to make sure everything's okay, tapi otherwise this phase usually settles down by week 14 or so, you can do this!
