pressure and lots of it

So I am laying on my bed with this pillow against my back and my legs are crossed I feel my baby pushing and I feel a lot of pressure in my vagina (sorry lol, going to be a first time mom) I felt pressure before, but now I get a shooting pain randomly and then tons of pressure I am 38 weeks and 3 days, I had a cervix exam Friday and my doctor said I am half a cm dilated and my cervix is soft and I am beginning to thin out.  Is there things I should be looking out for so I know labor is near... or is this normal could this possibly mean I might be getting to dilate more? I been doing tons of squats too, because I heard it can help a little with dilation. Sorry for this massive Paragraph lol.
