Aih sayang, itu normal je rasa takut dan excited macam tu! Untuk ectopic pregnancy, doctor biasanya akan scan pakai ultrasound vaginal around 4-5 weeks lepas last period, tapi sebab you dah ada history lain, doctor akan probably monitor you lebih closely and maybe scan awal sikit. I punya few mum friends yang pernah alami, semua depa cakap communicate je dengan OB/GYN you sebab timing scan kena customise based on your situation, jangan tunggu lama, call clinic sekarang je and tell them you're pregnant so they can arrange early scan untuk ketenangan hati you.
