Hi,
Welcome to ehealthforum.
Sometimes there can be incomplete rupture of hymen. Repeat intercourse can lead to complete rupture and bleeding. If you were during your fertile days or close to your ovulation time, chances of pregnancy are possible. Wait and watch for your periods. Look out for development of any new symptoms suggestive of pregnancy if you suspect chances of pregnancy. If you do not get periods within 10 days of expected period dates, or if you get abnormal periods, or if you develop any new symptoms, or if you suspect chances of pregnancy, you should consider visiting your doctor/gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately.
Take care.
