Has anyone dealt with irregular heartbeats after giving birth??? Long labor with 3 hours of pushing that had me exhausted to the maximum and ended up having a C-section.

Was seen by cardiologist and said it's normal to have these after being pregnant and all the hormones. I didn't have this issue after having my daughter 12 years ago but now having this issue after having my son last week.

If you had the same issue, how long did it takes for your heart to regulate?
