Overweight girls, did the normal Plan b work for you?

I had unprotected sex and took Plan B last night, I weigh 225 and apparently plan B doesn’t work if you’re over 175. Anyone taken it and weighed more than 175 and it was successful? I’m pretty worried. I was not able to get Ella (the plan B made for bigger people) because you need a prescription and I didn’t want to wait the whole weekend to take something.
