Pregnant?

So I had sex twice on Christmas eve, which was my last fertile day according to this app. Both times my boyfriend successfully pulled out. I was scared that he could've gotten pre-cum in me so I took a Plan B two days later. The day after I took Plan B, I had cramps and white discharge. I had that for about 6 days then it went away. My period should be here in 6 days and I am stressing tremendously because I don't have period symptoms yet? I usually do. I have weird cramping in my pelvis and bloating but usually I also have sore breasts and my cramps are different. :(
