Period? Or not??!!! (TMI-no pics)

So my period is suppose to start tomorrow or Wednesday according to my two tracking apps. I had VERY VERY LIGHT pink when I wiped about 3 or 4 days ago, but only when I wiped and it never got heavier. Last night, my husband and I had sex (nothing too rough!) and about halfway through I could smell the nasty period blood smell and my hubby pulled out and said "period's here..." We finished and when cleaning ourselves up, there was definitely blood. When I wiped, it looked like normal bright red-pink period blood. I threw a tampon in and called it a day lol. I went pee before bed and took my tampon out, ONLY VERRRYYY LIGHT PINK on the tampon. So I left it out for the night and threw a panty liner in my undies and went to bed. I woke up, nothing in the liner and nothing when I wiped after going to the bathroom...does it sound like there's still a possibility of being pregnant or should I wait a few days and see if AF actually does show up?? I'm so sick of BFNs!! :-(
