Sharp pain

Tee
So I am 27 weeks and 5 days. As of yesterday I have been having this sharp pain that comes and goes throughout the day down in my lower abdomen. Like it's right where my underwear would sit and shoots straight down into my vagina. I don't know what's causing it or what to do. I drink 10-12 glasses of water a day so I don't think it's from being dehydrated. And my little guy is super active all day long and that hasn't changed. Just wondering if anyone else has experienced this and what it could be from. Thanks!
