i have been trying to concieve for the past few months. last month before my period I had sore breast which is unusual for me. After i had my period the soreness went away and a week after my period the sore breasts came back and have been sore and getting more painful each passing day. i have been moody and exhausted and have gained weight. I even have a line from my belly button to my pelvic area. I also have been very sensitive to smells and certain food. Also a more disturbing thing is that i feel my body odor has changed. a smell ive never had before and quite unpleasant. I also have bad acne at the moment which is uncommon at this time. yes usually before i get my period i get a pimple or 2 but i have it all over my face. Is there a possibility that i am pregnant but the hcg hormone cant be detected yet? With my first and only child i had a feeling i was pregnant before my period started and took the test and it came out positive right away. I have the same feeling but negative results. any input or advice would help. thanks
