Irregular Fetal Heartbeat at 36 weeks

Went for my routine checkup and during the scan, my gynae detected some irregularities in heartbeat though the heart structural part shows no defect, did a CGT to monitor heartbeat and check for contractions. Baby is super active, now I’m just worried that something is wrong as she will assess the result and see me only next week. Has anyone went thru the same and if so, how was the outcome🙇🏻‍♀️
