Hi, I have sore sensitive breast, green veins. I feel bloated most of the time and I always feel tired lately, I have nausea mostly in the morning before I eat, and constant headaches. I do not have a regular period because of pcos, but last had my period January 14. Last sexual engagement was January 09. I have taken hp tests and they have come back negative, I haven t had a scan or bloodwork done. Is it possible that I could be pregnant?
