I am now 7 days late and I am very regular so this is odd for me. I have a discharge too and last week I threw-up 2 times, also smells are more prominent to me and I also have some back pain. The food thing too and i had some cramping for 2 days and then it was gone. I have taken 2 test and both neg, we have been trying for almost a year. I hope its true I just don't want to get my hopes up.
