Hi.. im new here.. I am currently 16 days late with my period, I have lower abdomen pains and im so tired I just want to sleep the whole time and I cant concentrate and I am a little dizzy, im thirsty the entire time but im not hungry.. I took a clear blue test when I was 11 days late and it was negative and I took it at 6pm.. so any advice please on what it could be or what I should do?
