Pressure?

I'm right under 21 weeks and I keep feeling a lot of pressure down there, outside and inside feeling I guess is the best way to describe it. It's not due to sex because we don't really do that. And it's also accompanied by slight cramping. Mainly when I walk. It's not a constant pain though. Anyone know what it is? Or had it?
