I had sex about one week ago and the guy came in me just a little bit, but of course I freaked out and got the pill. I took it about the hours later and had very mild nausea. This is my first time taking the pill (I don't have sex very often so I don't take any birth control either). I'm just worried that it may have no worked? I have a period every few months and I'm sure I was not ovulating when I had sex, but I still want to know if there is a better/sooner way to know whether I am pregnant or not. There was no spotting or any other side effects besides nausea.
