Please help stressing!!

So I have sex about a 5 days ago. July 5th, he pulled out and came on my chest but then I saw that the condom had broke.. this happened at 2-3pm and I took a plan b at 10pm that same day so it was within 24 hours. I had just gotten off my period 2 days from that day and I was not fertile I had 5 more days till I was fertile. I had some stomach pain after I took the pill but then I was fine. But today I wake up and I see I have a little spotting.. I'm supposed to be fertile tomorrow and I've been feeling really bloated sorta like gas stuck in my stomach. Then the whole day I had a little spotting like blood but then it would be brown and right now it's a little little bloody. I am stressing out like crazy I do not want to be pregnant and legit this is nottt the time for me right now. I am not on birth control either.. PLEASE HELP stressing like crazyyy
