What are the chances of me being pregnant? A guy and I had a "fun" night about 2 weeks ago and he used pull out (first time I didn't have protection). But because of the number of times we had sex that night I'm wondering and worried if the precum would have gotten me pregnant? My period should start soon but I am getting some lower abdomen cramps; I do not know if they are for the period of something else... Especially since I've never gotten cramps before.
