See mine feels like a dull ache as well but gets crampy. Not painful just annoying!
No blood or cramps. Just a dull ache.
As long as there's no blood tho of course
Honestly my nurse practitioner said it's normal to have cramping and aches in your pelvic groin area. I've been having the same I'm 14+5. Ask yours though.
Could be round ligament pains but get checked to be safe
