So on the week of the 18 my boyfriend and I did Anal sex for the first time. He came in me. I didn't think to get up and clean off right away. The next morning, I was discharging what I think was his cm. (The underwear around the anus area was soaked) I immediately got up and changed my clothes and underwear. I was ovulating (discharging slimy white stuff) the week of the 13. Could his cm/sperm somehow got off of my underwear and into my vagina overnight? My friends say it isn't possible...my period starts either the 28 or 29 of the month and last for about a week. For the past couple days I've been having slight cramps, a little irritable, and been kinda tired. But it's only the 23...Im so scared...Am I pregnant?
