Sharp abdominal pain in lower left side.18W

Chelsea
Im 18W and I've had sharp cramping in the lower left side of my belly since 8AM. Occasionally it will radiate around to my lower left hip and back. I googled it and got round ligament pain. I've had a bowel and have passed gas so I'm ruling those 2 out. I took a nap laying on my right side and it still hasnt went away. I thought cramps were a temporary on off thing not ALL DAY LONG. Is this normal? My OB office is closed today and I'm starting to get worried.
