I have pain in my breast on both sides. It starts at the nipple and goes all the way under my armpits to my back. I am unsure if this is a pregnancy or PMS symptom or something else. It's really uncomfortable and painful. I have about a week until AF but I am irregular so I'm never exactly sure when I will come on. I am also experiencing other symptoms including nausea, headaches and light cramping which comes and goes. Do you think it would be too early to test? I am about CD22. I would really appreciate any advice, thank you xx
