Salam! Ahhh I understand why you're worried, sayang. Tapi jangan risau dulu, please go see your doctor or go to the clinic/hospital ASAP, especially since you're 8 weeks and ada spotting + on-and-off cramps. Ini bukan something to guess-guess online, okay? They need to check you properly and make sure baby okay. Better safe than sorry! Sending you calm thoughts, let me know how it goes once you see the doctor ya.
