Unprotected sex + irregular period + plan B + BMI over 25. Am I at risk of getting pregnant?

So yes it was stupid of me to have unprotected sex and one thing led to another and it happened and I can't change that. I am fully aware of its dangers and possibilities of me being pregnant.
I have a very irregular period. I have a minimum of 3 periods a year. Its often hard to track because most of the time my periods are very light and short or nonexistent and sometimes I wonder if it was a period at all. For this very reason I've ALWAYS been very careful when I had sex or just not have it at all. Unfortunately today just happened to be the day I fell of the wagon and just let it happened, and now I've had unprotected sex.

About 1-3? hours after sex, I went and bought plan B to make sure just in case.
I started to read that plan B is less effective with a BMI over 25. My current BMI based on my height and weight is 26. So now I'm just worried.
I've read many forums and research findings and all other info on plan b that I sought creditable within the past few hours.
And yes I happen to be one of those cases where the guy "supposedly pulled out", but I'm not risking it, therefore I bought the pill. Also I've already read that pre-cm usually does not contain sperm unless they've already ejaculated before or haven't urinated. And I am positive that even if he "pulled out" in time or w.e there is that possibility that sperm entered me probably... worse case scenario..... yeah....
If my period was regular I would just wait for my period but since I don't know WHEN it will happen I'm just stuck here hoping that PlanB will work. My last period has was about 2 months ago so yeah... I'm already irregular and late as is.....
It's been a few hours now since I've taken Plan B and I'm not sure if I feel anything yet. But if anyone here is in or was ever in a similar situation I would greatly appreciate your input.

Hello Anonymous,

Thank you for reaching out to us with your concern about a possible pregnancy.

You have obviously done your research. For the benefit of our readers,
a research paper posted this month by two professors affiliated with Princeton University states: " Analysis of data from the two randomized trials... found that when compared with women who were not obese, obese women taking levonorgestrel had a significantly higher risk of pregnancy..."

"In clinical trials, contraceptive efficacy was reduced in
women weighing 75 kg (165 lbs) or more and levonorgestrel
was not effective in women who weighed more than
80 kg (176 lbs)".

Anonymous, as you know a BMI of 26 is considered overweight. My only suggestion is to have a blood pregnancy test done. With a history of irregular periods, I think it is your only option, other than waiting.
