Am I pregnant

So about 3 weeks ago I missed a birth control pill and the next day my bf didn’t pull out and nutted in me but he didn’t tell me until after. And then about a week ago I missed 3 pills bc I went on vacation and left my pack home. And then a couple days later I experienced this brown/dark brown period blood (ive missed birth control in the past like a month or 2 ago and I only got spotting never blood). And I looked it up and dark brown period blood indicates pregnancy but idk if it’s from that or missing my birth control. It’s also weird for me to have gotten my period in the middle of my pack even for missing 3 days because it’s always the last week. And YES I know I need to start being more careful with taking my pills
