My boyfriend and I had unprotected sex on July 15 and I think I might be pregnant and I think he mad came on accident. I've been having lower back pain (started yesterday 9-20) and intensified today, abdominal pain on the left side, cravings, nausea, headaches, very fatigued lately, tender breast and tenderness around my nipples, frequent trips to the bathroom, moody, and white and yellow milky discharge with an light odor. I'm not nervous I just wanted to know what are all these symptoms could be. I had one child before and didn't have any symptoms, but I did have discharge with an odor. Could I be pregnant?
