Sayang, please go to your doctor or clinic cepat-cepat ye, sakit perut during pregnancy kena check properly, tak boleh assume je. Even if it's just the black pepper, your doctor needs to make sure baby okay and give you the right advice, especially about any medicine.
Jangan ambil ubat sendiri dulu tanpa tanya doctor, ya? I know it's scary, tapi this is one of those things where kena professional check. Minta husband atau mak you drive you to the clinic sekarang, better safe than sorry untuk baby.
