Please help I need reassurance!

Okay so I'm putting pictures below to show what my cycle is because I have two different apps that are telling me two different things which I know they are just predictions but anyway so as you can see I had sex 4 times like week and the first 3 he just pulled out and the the 4th time we used a condom. Usually everytime we pull out, we get a plan B pill and that is why my cycle is all messed up because I've taken a plan b the past 2 months. Then just last night we had sex again and he pulled out but I had more CM yesterday so I figured I was more fertile so I told him to go get plan b. I'm getting an IUD this summer so I don't need people telling me I need a more effective form of birth control. I'm mostly nervous about the 3 days last week that he pulled out and we didn't get a plan b since I know they have to be taken within a certain amount of time. However I don't think I was ovulating those days despite what glow says because I had absolutely no cervical mucus. So what I'm asking is how high do you think my chances of pregnancy are?
