Freaking out

My cycle is four days late, and I'm freaking out. I'm afraid to take a home pregnancy test, in fear that it might come out positive. Me and my guy are always careful, but I guess we were a little too excited when we got together after not seeing each other for 8wks, and it was the day right after my last cycle ended, I thought I should be okay, but now, I shouldn't have assumed anything. I can't handle another baby right now, I'm totally freaking out!!!
