Am I pregnant? and should I take plan B

Hi!

So two days ago I️ had sex for the first time and we used a condom and he pulled out. The thing that worried me was that we had to take off the first condom and put on a different one so I’m not sure if there is a possibility of something happening then. Between the switch I️ also have a blowjob. Anyways, my period cycle is an average of 41 days but my period is still a bit irregular. I️ should be getting my period any-day now but I’m not sure if I️ should get plan B within the next three days.
