Can a first baby disengage...?

[babyignoramus]

Hi all,

I was told at the midwife 2 weeks ago that my baby was 3/5s above brim (at 31 weeks). But I woke up this morning and my bump is really hard and sticking out on both sides quite high up - as though the baby is lying transverse. Still getting kicks in the same place though - is the baby likely to have disengaged and moved that much...??

I don't know about positioning but my first was 1/5th at 33 weeks and bobbed back out by 35 weeks
