Spotting during sex

Omg how annoying is it when your getting it on and all of a sudden your SO looks down and says your bleeding WTF I'm on the pill and I hate when I start spotting between periods it's super inconvenient. So then we stop because we didn't want to make a mess we were in the car. (Not important) just venting. Has this happened to anyone else. It doesn't happen often but every once in a while my pills side effects rear their ugly head 😒 FYI my period isn't supposed to start for another 15 days and I have been taking the pill everyday at around the same time religiously.
