Jaydess side effects

Has anyone tried the new jaydess coil yet? I had it fit 3 weeks ago and am experiencing very extreme cramping and some sharp pains. It's possible it's pms because I am due to start my cycle this week but am worried it could be infection due to the coil. Could also be my body adjusting to it but that seems unlikely as it was fit 3 weeks ago. Scheduled a doctors appointment for tomorrow. If anyone else had tried the jaydess iud can you let me know? Thanks
