Could this finally be it?!!

My husband and I have been together for 5 years. We have been trying to get pregnant since we got married 2 1/2 years ago. Last year I went through 7 months of clomid shots and estogen pills. We were both tested. His test came back super. I was checked for blocked tubes and other things. Results, fine. We quit the treatments because they were more stressful than anything else we were trying. Since then my periods have become irregular and each month that I am late my husband swears that I am pregnant and one of his "boys" has finally cracked the egg. Each month we are faced with a bid disappointment. My last cycle started July 16. I started spotting very lightly on Aug. 16. It only lasted that one day. My breast are more sore than the usual "period" soreness that I get each month. We are in an unsually hot season here in NC and whenver I get into my after it has been closed up all day, my breast are in extreme pain when the built up heat in the car hits them. I have occasional nausea and this fluttery pulling feeling near my right ovary. I took a test a week ago and it was negative as every test I have taken has ever been. I'm not sure if I want to take another one now that I am actually late or wait another week to see if my period is going to start. Each month that I do get my period seems to be less of a blow to me than my husband. I am learning to come to terms with our lack of children. Sometimes I think God has other plans for me, He just has let me know what they are yet.
