Welcome to HCM,
After going through your history,foreplay involves intimacy,and if there is enough force of finger or private part then as you are virgin a thin membrane called hymen
may get torn and very little bleeding can occur, if you have not done any penetration then still you are virgin but as you description is not clear so it is not clear if any semen was there or not some times even pre ejecculation fluid contains sperms.
There appears to be risk of pregnancy
almost nil but rarely it can as it can not be said with 100% surety. Even if rare chance Emergency contraceptive pill
may be taken with in 48 to 72 hours and if time has passed then wait for your period if you do not get take urine pregnancy test.
Please take care in such foreplay because in such cases couple reach point of irreversibility and undesirable result is out come.In case you go ahead then please practice safe sex
