Cervical Lenth Ultrasound

Ang • Mother to Xavier & Naomi👨‍👩‍👧‍👦❤ Baby #3 due February 2020 💚

Has anyone had an ultrasound to check on your cervical length? I have one scheduled Monday, I'll be 31+5. Is it only a transvaginal ultrasound or an abdominal ultrasound as well? I remember my midwife telling me when I was 22 weeks that my placenta was near my cervix opening and they'll check it again at 32 weeks. Will they check for that as well, you think?
