Vagina stabbing pains

I'm 38 weeks today and a ftm and I've noticed the last couple days that I've been getting sharp stabbing pains in my vagina and some rectum pressure (sorry for the tmi) and it hurts a lot.. What can this mean?

Update: had my first check for dilation today and I'm 1cm and baby is low.. Hoping I have him soon.. Explains the pain lol..
