cervical pressure?

Kayla • Due December 28, 2016!
Hey ladies! 
I'm 31 weeks + 2 days & recently I have been feeling a pressure on my cervix.. Well actually I don't know how to explain it at all but that's all I can come up with. It's kinda like my baby is pushing on my cervix for just a few seconds every few hours. I'm a first time mom so I'm just wondering.. Is this normal? I don't know what Braxton Hicks feel like but could that be what I'm feeling?
