likelihood i am pregnant?

i am going to take a test in a week (when recommended) regardless of what is said here but i’d just like to either be reassured or be given a reality check here
Two weeks ago my boyfriend and i slept together, it was our first time and he didn’t use a condom for around a minute before putting one on. I took a plan B that same day out of worry, however i was wondering the chances i am pregnant? he didn’t climax at all, doesn’t think there was pre c and i read somewhere that pre c will only have sperm in it if he has ejaculated prior and there’s some left, which he hadn’t

You’re not pregnant. Sometimes the plan b can delay your period, try not to stress either as that also delays your period. If you have been taking any sleeping tablets also stop those. Try and relax have a bath tonight and you will be absolutely fine❤️
