Okay so I have had my implanon out for 4 weeks today and me and my fiancé are ttc. We have had unprotected sex before and after removal. I still have not gotten my period but have had slight spotting and mild cramping but no period for almost a week now. I have been really moody and felt nauseous. Could this be from the removal or could I be pregnant?? I have taken two tests but both have been negative. Is it too soon to know if I am? Should I be worried?
