I am a week late for my period. I noticed that I have been nauseous and slightly crampy for the past week. There are some days I feel like I have started, ran to the bathroom, and find that it's only clear discharge. I also go to bed hungry, wake up hungry, and since I work in fast food, I am always snacking on like green peppers. Thought/think I'm pregnant, but got 2 negative tests. One being taken first thing in the morning. Not sure what to do now..
