Hi 
    Today I'm suppose to start my cycle and I have not yet. I usually start early in the mornings every month. It's weird I have not yet! I'm not cramping I'm just really sore down there and my boobs hurt and are swollen! I'm so scared to take a pregnancy test. I'm not trying to get my hopes up and then I get a negative test! ;( my husband and I have been trying for three years. I'm not giving up at all! It's just so frustrating sometimes!!!
