I am a 26 year old female my last menstruation was 6 days late when it finally came the Saturday night it was finished the Sunday morning. My next cycle is due in three days time. I am currently experiencing sivere breast tenderness, swollen/enlarged breasts and my nipples are hard and erect. I am getting terrible headaches on a very regular basis, have lower back ache, mood swings i am suffering from nausea, i have picked up some weight. This all has been going on since December 2012 after my so called period started. I went to the doctor today due to me getting indigestion, he tested me for pregnancy but the test was negative
