Negatif pregnant test

Aww, I understand lah the anxiety, I've been there too, and a few of us mum friends also had delayed periods that turned out to be nothing to do with pregnancy. Nine days late is still within normal range honestly, hormones can be moody like that, stress or changes in routine can push things around. But since you're worried, maybe go see your GP or gynae to check, could be anything from hormone imbalance to just a late cycle, and they can do a blood test if needed which is more accurate than home kits sometimes. Don't stress yourself more lah, your doctor will sort it out quickly.
