spermicidal condom broke and I took plan b within an hour

Someone please ease my mind!!! My boyfriend and I decided to buy the new ultra thin condoms with spermicide, so I   bought them and he broke the condom. Right after, we raced to target and I took plan b within an hour of the accident. I am over weight, maybe even obese, I haven't weight myself in a while, I read that weight doesn't effect the function of the product, but right now I am scared and thinking of every possible bad thing that can happen. This app is telling me that I am 4 days away from my fertile window and I finished my period last Wednesday, and I also read ovulating, the pill is pointless, but to my luck, my period ended fairly recently, the spermicidal lubricant Is said to kill off most Sperm and since I am fairly far  away from my period, are the odds in my favor? I also shoved three tampons in my vag to clean out and semen in left, so maybe that did something? Am I doing this right? I am 17 and have been having sex for about 2 months now and using condoms that thankfully haven't broken and have been successfully used, this is the first and I can't sit still, so will someone please tell me it's going to be okay and I'm not pregnant?
