okay so, i started feeling real weird the other day at work and was really nauseous, which i then proceeded to throw up. well the past few days ive been off and on nauseous. but extremely hungry. when i eat about 10 minutes later my stomach is literally growling because i feel like im starving! a few days ago i got what looked like a faint line on a test but didnt really pay mind too it because apparently the test i used is bad for false positives. today i got another super faint line on a different brand test. and around an hour ago my body just felt sore. my back started hurting & the lower left part of my stomach has a pain. is this implantation or?? my period isnt due for another 2 weeks, ovulation was supposed to be yesterday but never occured & my last period i was on ended super early, but me and my boyfriend were sexually active throughout my last period. ive never felt like this 2 weeks before my period is due. these are the test ive taken. the last one is apparently bad for false positives.
