Condom broke / plan b

On Thursday I had sex with my boyfriend and our condom broke I took plan b Friday morning . I know I was not ovulating , I ovulated 2 weeks ago (took ovulation tests) I actually took another ovulation test the day I had sex and it came out very negative . I just took plan b to have some piece of mind because I know I would’ve been stressed if I hadn’t . I am supposed to get my period tomorrow and I’ve been getting all the symptoms. My question is if I get my period on these following days does that mean I will not be pregnant ?
