I just need some advice

I'll try and keep this short. So basically I got on bc and I put on just like the directions said to and waited the correct amount of time and then had sex with a condom. I let him come inside the condom but the condom slipped a little but didn't come completely off and there were no holes or anything like that. Since I'm new to the whole bc control scene I should I'm just wondering if I should be worried or not. Thanks in advance
