Light cramping

Hi mommies-to-be! I just had a transvaginal ultrasound today (I'm 6 weeks and 2 days) and got to see my little baby and its heartbeat! However, now I'm having slight cramps every now and then. Can anyone let me know if this is normal due to having the probe in me? (They did the ultrasound to rule out ectopic). No bleeding-just dull cramping since. Any advice is appreciated!
