My period started 1/19/13, and I had relation with sperm around and in my vagina on 2/1/13 with saliva involved. Could I be preg? Need to know quick!

Use plan b. You have asked this question in various forms and each doctor has told you that yes you could have gotten pregnant. If sperm is in the vagina then pregnancy is possible. Since this was less than 72 hours ago you should buy Plan B over the counter at any pharmacy to decrease your risk. Then check pregnancy test in 10 days. See doc for birth control to avoid these scares.
