if the last time i had intercourse was last saturday is it possible to already have symptoms of pregnancy. just a couple of days later my breast got really sore. that wouldn't bother me except for the fact that it's lasted for 5 days already. i have had some stomach pain and discomfort but i get that sometimes becouse i do have a problem with ovarian cyst at times. Then at the same time if it's not from that what would couse you to have sore breast. i shouldn't start my period for about another 2 weeks. if you have any thought let me know. thanks
