So... Two weeks ago today, I was in the middle of my "fertile cycle". My boyfriend and I had sex. Okay, whatever no big deal. Well.. I'm not on birth control and he didn't pull out(he usually does). I've already got a kid so I should know by now how it works. But my son was also planned with his father(whom I'm no longer with). I know it's still a little early, but I'm wary that I could be pregnant again. I bought a couple tests on Tuesday to use in case my period is late. It's a two pack. Should I go ahead and use one in a few days/week(or so) or no?
