Some lower left pain

I've had some discomfort on the lower left side of my abdomen (it feels like my overie) it does not really hurt but it comes and goes and feels more like discomfort than pain.ive had this discomfort since last night and hasn't gone away. also, im about 5 weeks preggo haven't gone for my first dr appt yet it's on Monday. Does anyone know what this pain is and of its normal? I'm a bit worried since it hasn't gone away. It hasn't gotten worst either btw
