Okay so Ive been getting sick for about 2 weeks and i started cramping but there are still 11 days until my period's due. I took a test a few days ago but it came up negative granted i took it late at night and i went pee like 10 minutes before that (i know i know but my boyfriend wouldnt shut up). My period tracker says i already got done ovulating three days ago. Ive been having headaches and lower back pain.... I dont know whats going on could i be pregnant?
