I do not know why you assume that this is a hymenal rupture. Even if it is it that is usually self-limited event and shouldn't recur. You do not say whether or not you're a midcycle but a small bleed at midcycle is not unusual. It is also not unusual for the body's normal rhythm to get a bit disrupted on vacation.
If there was an injury
and all that happened was a little bit of bleeding that went away after a few hours then enjoy the rest of your vacation. If however there is swelling, significant pain, a large bruise
or increasing pain I suggest you call the home country counsolate for where you a
re, or call home to your travel agent and ask who they recommend for medical care. Some resorts may also have a doctor to see their guests.
I hope this is helpful.
