welcome to Healthcare Magic.
Although cardiac illness is uncommon in your age group but it is better to get examined for it and get your BP recorded to rule out high BP.
As you are already having period and if you are having abdominal then these symptoms more likely due to Dysmenorrhoea or Hormonal
imbalance. For that you can visit nearby gyenecologist.
For symptomatic relief in presence of abdominal pain
, you can take analgesic
Wish you good health and all the best.
