Ok someone tell me what they think

Just gonna throw it out there this is a weird story.

My and my boyfriend went out to the club came back and he was drunk and we attempted to have sex.... literally during sex like he was still in me he falls asleep😅 my period is suppose to come tomorrow and I’ve been on BC for about a year now but i went to the bathroom and there was very light colored pink blood in my underwear. I’ve never missed my pill and always take it on time. My concern is that when he fell asleep he’s assuming he finished and if he finished it would’ve been in me. I didn’t feel any different down there if he did finish in me, I didn’t feel like extra wet or anything but I just am paranoid cause we don’t know if he pulled out or not and my period came a day early. Someone please ease my mind or tell me what they think.
