Low lying placenta

Ramya

Went to doc offz today for 32 weeks 3 days ultrasound scan to check placenta. And told that I’m 2.3 cm away from cervix . But my doc suggests it should be Atleast 3 cm to try vaginal delivery . She told me to do Ultrasound again in 36 weeks .. Is there any chance that my placenta can move up to 3 cm before 36 weeks scan ?
