My period is always very regular and this paticular cycle it's more than a few days late. I'm sexually active but the last time I had sex was a few days before my last period with a condom (that was in my wallet for a while, i wouldn't be surprised if the heat wore it down). Anyway, I haven't had sex since before my last period and I just took a test and it came up negative, which I was expecting because I know the chances of me being pregnant are slim.
