My girlfriend ended her periods on 27-11-2017 and the next day we had foreplay like thing. I was wearing a condom and i ejaculated. Later 4-5 hours after this i took the same condom and threw it in dustbin. The condom was wet and hence my finger tips got the same. After 15-20 minutes I rubbed her vagina while she was wearing underwear and cotton night dress. Is there a chance of pregnancy? We both are feared. Please guide us. Thanks in advance.
