Chest pain and shortness of breath. took blood pressure was 126/103 then normal yesterday then today 106/100 and plus 100 machine said that was great?

It is unlikely that: the blood pressures you are reporting are accurate. A pulse pressure of only 6 (106/100) is unlikely in a 26 year old woman in the absence of severe medical conditions of which you would certainly be aware. You need to see a health care provider for an accurate assessment of your blood pressure and the symptoms that are causing you concern.
