What do you think...

I have been Ttc for almost 2 years and have been diagnosed with secondary infertility. We are starting IUI treatments in a little over a week. However, this month I have a little bit more hope for some reason. My breasts are extremely sore and my veins seem to be more predominate right now. I know the breast tenderness could be a sign, and they say that veins are more predominate later on in pregnancy, but what do you think.... Could this be a sign for me?
