HI, thanks for using healthcare magic
Stress can affect the blood pressure but you should still continue the medication till your doctor suggests otherwise.
In terms of the pulse , the normal pulse rate is 60 to 100 but persons who are fit may have pulse rate below this. It occurs because their hearts are beating more efficiently.
If you are very physically active, this could be the reason for your slow pulse rate.
If you are not physically active and you are having symptoms related to this pulse rate (
dizziness, feeling weak , clammy, sweating,
fainting etc), then you should be seen.
IF you are not having any symptoms, then you can consider monitoring unless you are still concerned.
I hope this helps
