lower belly & vaginal cramps

I'm 12.5wks. haven't had a dr appt since 7.1wks & my next appt I'll be 15wks. I've been slightly crampy past couple of days but today more so. lower abdominal cramping slightly feels like period pains but can't tell if it's that or ligament stretching. it also feels like baby is low & heavy but I know the heavy part is impossible. also I keep getting sharp vaginal cramps. is all of this normal pregnancy pains or should I go to drs tmrw? or should I just wait it out til next appt??

NO bleeding btw
