Hi. These are not really pregnancy symptoms. Early pregnancy actually often produces few symptoms in women (and none in men. :>) your boyfriend feeling low would have nothing to do with pregnancy)-- with being a bit more tired than usual being the thing you hear most often. At around 6 to 7 weeks into a pregnancy, women will start to report morning sickness and breast tenderness. Morning sickness is not pains, severe throwing up typically but more a feeling of being nauseated that comes and goes. So, you really do not describe pregnancy symptoms. Have you considered seeing a doctor? I would do this if this persists. You at have a gastrointestinal issue that needs to be sorted out. And a pregnancy test is another route to take if you want to be 100 percent positive you aren't pregnant. good luck
