TMI! Advice needed!

TMI!
So I have been feeling weird down in my vagina area all day. So finally I checked to see what was going on. Inside very close to the hole downward is a bouncy ball sized knot. It feels uncomfortable but does not hurt when I touch it.  I'm 11 weeks tomorrow but not sure if that has anything todo with this. No spotting.. Should I be worried?? Idk what it is or could be?
