I don't understand my body anymore.

Hey ladies. So, My period started on April 9th. And I'm not quite sure when it finished? ( It's also been kind of clotty. My period has never done this before. ) Because about a week or so in, it wasn't a constant flow like usually. Every day since then, I've been getting random waves of orange-red discharge. Would that count as a period? Secondly, yesterday I gave head to boyfriend, he wanted to try thrusting behind a few times and pulling out, (within a condom) and his pull out game was strong. He had to jack off 30 seconds before. I was worried about the pre-cum, so I got plan b today and took it around 3:30, but what's gonna happen now? Will I still possibly be pregnant? Will any incoming periods be affected? Like I'm just so confused right now 😩😩😩😩
