Tahniah sangat on your pregnancy, bestie! Cervical length screening tu boleh buat kat most private hospitals atau fertility clinics, lepas tu boleh tanya OB-GYN kau juga, ramai yang offer. A few of my mum friends did it not because of previous miscarriage tapi sebab worried, especially after trying so long, so tu totally valid reason! Since you're already 5 months, I'd say cepat consult your doctor directly, dia boleh assess if you need the screening and refer you properly, sebab sometimes ada specific indications or timing yang better. Don't over-stress yourself lah, the fact that you're this proactive is already good, but let your doc guide you on the best next steps, okay?
