Help?

So me and my s/o had sex on the 1st of this month and the condom broke, he nutted in me. I’m on the implant, and I tried to get a plan B from the doctors but they said I would be fine. I had my period the 8th and I was on it for 15 days and it wasn’t to light but it wasn’t really heavy either. I haven’t had any normal pregnancy symptoms but I had a day of morning sickness but I never threw up and it lasted about 5 mins I drank something the other day and it didn’t taste right but I had it again and it tasted normal, and I’ve been gassy but other than that nothing...I’m nervous, and scared...
