I haven't gotten my period since Nov. 23. I took a blood pregnany test on Jan. 11th but it was non pregnancy. Before I got the results back from the pregnancy test my doctor checked my cervix and scheduled me for a sonogram in two weeks. (this Friday) I am really scared because I don't know if I'm pregnant or not. I have been feeling nauseated, tired, hungry more often, and my breast have been feeling tender. Can someone help me please and tell me what you think*
