One-sided cramps

Alexandra • Mother of one amazing 19 month old girl and trying for a second.
Anyone have any experience with cramps only on one side? I have been having cramps on my left side only on and off for the past 2 weeks or so. I am almost 8 weeks pregnant now. I am pretty sure I ovulated from the left as well. The cramps feel very similar to menstrual cramps but only last for about 15 minutes or so and then may not return for days. I am usually sitting and not moving when they occur. I know cramps are normal during this time of pregnancy but it makes me nervous that I am just cramping on the left. Please let me know if any of you have experienced something similar. My first appt. isn't for another week.
