Can round ligament pain be constant?

Past couple of days I've had an annoying dull ache which occasionally feels like a pulling where I would normally get round ligament pain. When I first started getting it it would be quick and sharp and when I moved too quickly, now it's always there but very very mild, just constantly throbbing almost and if I bend too quick then sometimes it'll become sharper. I'm just unsure if this is still round ligament pain or not because everywhere I've read says round ligament pain only lasts for a few seconds to a minute... I'm 11 weeks.
