Just wondering if anyone thinks they can feel their BH 'working' for them? Or has experienced this happening?

I have had a couple of weeks now with some really random patterns...one day nothing at all, other days I will have hours of uncomfortable BH. The other night they came from 4pm to 6am and some were uncomfortable enough to wake me up. I got up...and they went away

Sometimes particularly with the good ones, I feel pressure down below .. I don't know how better to describe it. It's not constant, comes & goes mostly with the BH. Also at times I feel a tingly, or tickly feeling in the same area which is unrelated to BH.

Do you think they could be working already even if I'm not in labour? I haven't had a VE at any of my antenatal appts so have no idea if I'm dilated or effaced...I have not asked because I figure with bub no.4, it doesn't really matter...right?
but...it would be nice to think things are happening even if very gradually... I am hoping to VBAC this bub & need to avoid induction

I have gone over with all the others..was hoping this one would be different but unless these BH amp up I don't think it will be, and atm they are far too random for me to get excited about.

Also, bub is not engaged yet - I know that doesn't necessarily mean anything again given that this is bub4 - but sometimes I could swear she feels lower and the pressure down there becomes uncomfortable, also it's almost like I can feel her shoulders resting on my hips - I really hope this isn't the case though because that would mean she has massive shoulders ...
I haven't experienced this before so i'm a bit puzzled as to what it is, whether its' just her moving about or if she's trying to 'get down'?

Any advice or opinions please! thanks
