I had a period in oct, 2 in nov, and awaiting on dec. My period wasn't scheduled to come on until Dec. 11th. I was spotting on Oct 6th, Nov. 3rd, and Nove 28th. Could i be pregnant? I feel nauseated, fatigue, headaches, irritability, cravings, can't stand certain smells. I feel all of the pregnant symptoms but i took 2 pregnancy test in Oct and they were negative. Could i be pregnant now.
