You might be. Use birth control devices if you engage in sex again, on the chance that you are not pregnant and wish to stay that way. I had 2 weeks of negative tests before a positive one. Oh, and do not assume you are not pregnant because you are not feeling famished, queasy, or anything else. I didn't have any of the 'usual' symptoms until the end of my first tri-mester; swelling ankles for two weeks in month 3, craving cinnamon during month 4, and excessive urination in month 8. I never had morning sickness and felt the best I had ever felt. So, please, do not just trust the 'symptoms'.
