Wa'alaikum assalam! Congrats on the pregnancy, mama! For makanan, yang penting makan yang balanced, protein, vegetables, fruits, and whole grains la. Banyak-banyak minum air, take your prenatal vitamins (especially folic acid, super penting in early pregnancy), dan makan foods yang kaya iron macam ayam, daging, atau leafy greens. A few of my mum friends swear by eating little and often kalau morning sickness tu mengganggu, roti, biscuits, fruits sikit-sikit membantu. As for intimate relations in early pregnancy, it's generally okay for most pregnancies, tapi since tiap-tiap mama's situation berbeza (especially first trimester), better ask your doctor or midwife about your specific situation, ya, they'll give you peace of mind!
