Hi, Today Just All Of The Sudden I Feel Chest

Hi, today just all of the sudden I feel chest pain on my right side all the way to my back. It hurt for me to breath, feel like being stab. I checked my blood pressure and its 107 /66. I'm currently on medication for blood pressure. Usually my blood pressure is normal since I'm on medication. I'm having my period at this moment is it possible because of it my blood pressure is kind a low ?
But what make me worry at this moment is my. Best pain, its really hurt.
