The last time I had sex was on 12/22/2011. I had what seemed like my period on 01/05/2012. Since then, my breasts have doubled in size, are very tender, I feel nausiated, had some spotting on Monday and Im having trouble sleeping. Believing that I could be pregnant I took a urine test last week and again on Tuesday- both were negative. Despite the results, I still feel like I am. Is it still too early to tell? My period is due on the 5th of February.
