I have been expiriencing chest pain especially under right brest shortness of breath could this b due to my recent coming off birth control HPV vaccine or oil pulling detox?

Unlikely. Go and get seen by a doctor. There are many possible causes for this and some which can be severe. Get this checked thoroughly and get an answer to the cause asap.
Oil pulling. May be a sign of other larger health issues going on. Consider visiting your doctor. Not oil pulling. I've got lots patients that do it. Never heard that from oil pulling. My guess would be hormonal.
Not bcp or hpv. I doubt if your symptoms are from birth control or the hpv vaccine. I do not know about the oil pulling detox and would have you see your physician for further evaluation.
