Plan B weight limit?

I weigh more than 150. Maybe around 160 or 165 I think I’m not 100% sure. Anyways I took plan b a few days ago and am just recently learning that weight can have an affect on it’s results? This is the first time I’ve ever had to take it so I didn’t know. I read the fine print but never saw anything about a weight limit. I took it less than 12 hours after unprotected sex. It was maybe 6 hours after the unprotected sex that I took it. Is the plan b going to work? Or is there less of a chance of it actually working? Please help if you can I’m freaking out
