I think that I have tricked my hormones to thinking I am pregnant when I'm actually not! I want to get pregnant so bad for the last time! My boyfriend had a vasectomy probably 8yrs ago. My breast have been really tender and feel heavy. Been feeling nauseous and every thing you can think of that comes with pregnancy the mood swings. In 15days thoe I'm suppose to start my menstrual. Has any body else felt like this?
