I and many other women have felt used during pregnancy, especially during the first quarter. As others have said, is not the only reason a woman could be a symptom. It would definitely pregnant and sees no change in the breast. I agree that you can not guess the symptoms alone, and you should give it a try when you are ready. If you have insurance, it may be cheaper to go to medical tests. If you do not have insurance, local public health unit can provide pregnancy testing, free of charge or at reduced prices
