Hi,
Welcome to ehealthforum.
Any vaginal manipulation in virgin involving penetration (be it finger, foreign object, or penis inserted in vagina), can lead to hymen rupture and loss of virginity. The hymen once ruptured cannot heal itself on its own. To confirm if hymen is intact or ruptured, visit your doctor/gynecologist for a thorough examination, further evaluation & assistance. You can also consider discussing with your gynecologist about option of getting hymen repair or hymenoplasty done (if needed).
If fingers had pre-cum or semen on them (and if you were close to your ovulation time), chances of pregnancy are also possible. If pregnancy is suspected, visit 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).
If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
