It is good to hear that you used protection. As long as you were on the pill or other method to prevent pregnancy. As long as the condom did not break and was used properly, you should also be okay.
When the hymen is broken, it can spot a few days to a week afterward. "Popping the cherry" should not increase the likelihood of becoming pregnant.
It would be more of a concern if you were late for your period, as this can be a sign of pregnancy.
If you experience discomfort, this is also normal. If it persists for a long time or gets worse, i would see the doctor, but you should be fine.
