Ok, advice needed!
I am 30+4 (first pregnancy) and for the last day on and off, mostly on
I have had this weird pain which I thought was my baby moving differently at first, but im not so sure now!
It feels like someone is shoving a knitting needle up there and prodding me about - and sort of like there is a big bubble up there which then dissapears - sorry if TMI (or if I sound totally mental)
It happened a lot yesterday, and now that im up its happening again, it actually makes me jump and swear and its really sharp! it feels like she has shovels for hands and is trying to dig her way out - which i sincerely hope she isnt! I have no other symptoms at all by the way and feel fine otherwise.
I googled it and came up with stuff about effacement - having not done this before can someone tell me if this sounds vaguely like it, do i see midwife or not? 
Thank you!!
