Super light cramping

Hi ladies, I'm almost 14 weeks pregnant, and for the past couple days, I've experienced extremely light cramps on and off. It isn't bad at all and I don't think the average person would notice it. I've had spotting in the past (Friday morning was the last time,) and every doctor says it's normal. I had a Pap smear on Friday which was really painful. Is this normal? Do I need to call the doctor again? Even though I'm relieved when I go in and hear the heartbeat of our baby, I feel so silly for calling and freaking out so often. Is this okay?
