Change of position chances?

My baby is in position to be born vaginally since 34 weeks (vertex position). Well, today (38wks+5) I felt my belly move in a peculiar “harsh” way and been feeling kicks in my right side of the belly.

I have an appointment on Wednesday with my OB but is there any way he might changed to breech or another position? This is making me VERY anxious and literally wanting to cry because I’ve prayed and wish for a natural birth. 😫😫

Hope you can ladies help me ☹️
