2 weeks of on and off cramping

2 weeks ago I was having pinching pains on the sides of my stomach and was also experiencing some other symptoms like headaches, now the cramping has continued for 2 weeks now with a pressure feeling but no sign of my period? I also had watery CM when I first noticed the pinching cramps, does anyone know what could possibly be happening? Last night the cramps were pretty strong every time I would stand up

I also have irregular periods but usually only cramp 2-3 days before I start
