LATE!!

My period is 3weeks late it's been late before by 4days but never this late. My partner and I have sex almost every day, we try new positions and just have fun with sex every time. I enjoy it with him but we don't use condoms so he does the pull out method and when he pulls out it's slow. I took a pregnancy test and it was faint lines.... CAN I BE PREGNANT?!
