hello.. I haven't had my period for about 1month and 2weeks.. ive been getting these tight and sharp cramps in my lower stomach and my breasts are tight and bigger than usual. my nipples are sensitive and is uncomfortable when my bf touches them. I get these mood swings here and there, I feel light headed and I get these headaches that come and go. my lower back is sore majority of the time and I feel tired almost everyday now even if I sleep in about a few hours later I feel tired again, exhausted and drained out, few weeks ago I went for a jog around the block with my bf and I got this intense sharp pain and felt so sick I wanted to vomit. It was like a pain I get when I have bad period cramps... Iv taken a pregnancy test this week and it come out negative. I hadn't eaten red meat for over 2-3years and recently for the past month iv been craving red meat..big mac was my main. I hated steak and for a whole week all I wanted to eat for dinner was steak. i only use to eat chicken and every time there was chicken around i would always be the first to eat it.. i don't have that taste for chicken as much as i use to. i use to just drink water no fizzys and lately ive been craving diet coke.. am i pregnant even if my test came back negative? please help
