I got my period on nov. 25th, it was about 2 weeks late and i dont have irregular periods, it only lasted for 3 days lighter then normal and they usually last about 7-8 days. Ive been nauseous all the time, no vomiting, urinating more frequently and sometimes have to sit there a lil longer to push it out(not a bladder infection, been checked) around the week right before and into my late mini period my breasts were sore but dont give me much trouble now. I have taken 3 tests in the last week and all came up negative, but most the woman in my family dont show on them very often. My sister who was pregnant last year showed me her stomach around 16 weeks in, she slightly leaned back and barely shifted her hips n her ab muscles shifted from one side to the other acoording to how she moved and i noticed 2 days ago that my stomach is now doing this as well. Do i just not have high enough levels to show on a test? Why would my abdominal muscles be moving like that if im not pregnant?
