My last menstral cycle was the first week in April. I ve taken three home pregnancy test and they were all negative. The thing that worries me is that I m a huge chicken eater. I usually eat it almost twice a day. These last two weeks or so I have gotten nauseous from the smell of chicken and other random times throughout the day. My appetite has increased greatly and for the first time in my life, my nipples are tender and sore. Could I be pregnant and my body not be producing enough of something to show up on the home test, could I not be far enough along, or could there be another possibility?
