Hello everybody. Wondering if antbody out their could help me. We have been trying for a baby for 2 months. For the last 14 days i have been experiencing breast tenderness and for the last 10 days been experiencing abdominal pain and lower back pain. The last 5 days i have been feeling very tired and using the toilet a lot. I am due my period tomorrow but today done a test that said negative. What else could these symptoms be if i aint prgnant??
