Alahan atau morning sickness is super common dalam early pregnancy, tapi honestly tidak semua orang kena, some of us just bertuah! A few of my mum friends didn't have any nausea at all, jadi definitely normal. That said, since you're only 7 weeks in, hormones still settling, so it might appear later or you might just skip it altogether, setiap pregnancy is different. Kalau you're worried or ada symptoms lain yang strange, best to check with your doctor just to be safe, tapi no alahan alone is totally fine!
