1st Baby

Today should be my 7weeks of pregnancy, still waiting for my first checkup on 30/4.. Is it normal headaches non stop and feel loya? Bila time nak muntah, i have to sedawa banyak kali then baru muntah keluar.. Any advise to makan apa.. MIL ask to not skip any ubat from doc, unfortunately belum dapat jumpa doctor betul2 lagi.. So tak tau what good for baby and apa yang boleh kuatkan baby..
