i recently god my period, but it was not normal. mostly just spotting. no heavy flow days. I had sex a couple weeks ago. I went to have a pregnancy test done, because i am having the nausa, gagging, almost vomitting, and stomach pains. The results to the test were negative. I am also craving foods in the middle of the night. NOT NORMAL FOR ME. as far as my period goes there was also no small blood clots that are normanl with periond. I normally last five to seven days, but this time i only went for. Again not normal for me. Could I be pregnant, or does this sound like another medical problem?
