About two, maybe two and a half weeks ago, I had sex twice in a span of two days. I've been on birth control for the last four months or so, and I have been pretty consistent with taking my pill -- maybe being up to two hours late in taking it, and having missed it once. While having sex, we also used a condom. This week I am expecting my period, and tonight I began spotting.

Now, with all of this in mind, it seems that I shouldn't worry about pregnancy. Still, I'm a little paranoid as I've heard of some scary stories involving young girls getting pregnant while they're on the pill, etc. And I know that implantation spotting is still possible up to the week of your period. I suppose I just want to know if an extremely light period is normal. I'm a little worried, only because my flow isn't quite as heavy as usual.

So: am I at risk for pregnancy?
