hello and thank you for asking HCM, I understand your concern. Your didn t mention if you were sexually active, becuase your symptoms could be connected with pregnancy. So if you are sexually active, my advice is to make a pregnancy test and if it is positive or negative to visit your gynecologist to start with prenatal care if it is positive, or to check while you have no periods if it is negative. If you are not sexually active, than visit your GP to make blood test to see wheter you are anemic or you maybe just have low blood pressure. I hope this answer was helpful to you.
