Nervous About Plan B

I recently had sex with my boyfriend and the condom slipped off inside of me, he didn't cum so I didn't worry too much or take plan B, but about 5 days later we were together again and the condom broke, again he didn't come but this time I took Plan B just in case, I'm still really nervous and don't know what to do, how can I calm myself down until my period either comes or doesnt?
