Chances Of Pregnancy After a Hand Job

Patient: I know this sounds silly and i am probably overthinking but i am really worried and stressed that i may be pregnant; the other week i gave my boyfriend a hand job when he ejaculated into tissue (i was on the minipill and on my period)… afterwards i am sure i washed my hands but not sure if i done it properly. Is there any chance i could have gotten pregnant?

Symptoms: Cramps (although this may be due to me having a cold/cough)

Doctor:
