question about stitches

so i was at school today (7 days post op) and i went to the bathroom and there was a little bit of blood on the left side (kinda near my frenulum area but not where it was removed). i cleaned off the blood and there was a small gap (im guessing one of the stitches popped off) and its not actively bleeding. the gap is just white im guessing tissue and pretty dry, but im a little worried. will it be ok? did anyone else have a problem with something similar and how did it turn out?
