Only a doctor can tell you the correct position of your baby. Contractions that are not persistent, intensify as they progress and become constant are probably just Braxton Hicks contractions, they are more so common at later hours of the day and night. If they go away, probably the case.

Your midwife will be able to tell. I guess you will have an appointment soon :)
