3 weeks, 5 days .. Weird pain

AG
This is my first pregnancy and tonight I've started having weird pains. The pains are hard to describe but feel like they're inside me? Kind of following the path up my vagina through my cervix .. It's almost like an annoying dull pain and the entrance to my vagina is also kind of having the same pains, but not to the touch, just I can feel it. It's not excruciating but enough I've noticed and don't know what it is. Is this kind of pain normal at this stage? Hopefully this makes sense. Thanks!
