Hello dear
I understand your concern
As you not sure about the sperm felt in vagina or not.
There may be chance that some sperm can enter in to the vagina.
Again if hand contacted very near to vagina, there may be chance.
But
pregnancy also depend on the how much amount of the sperm touched to the vagina and fertile phase of the cycle.
If you did sex in the fertile phase of the cycle, then there may be chance of the pregnancy.
In that case, I would suggest to take
I pill as early as possible with in 72 hour s of sex.
If 72 hours has been crossed then wait for period.
if period will delay by the 8-10 days then go for urine pregnancy test and or blood
HCG to confirm the pregnancy.
If you will be pregnant then still you can terminate the intrauterine pregnancy by
abortion pill under the supervision of the gynecologist.
Hope this may help you
Best regards
Dr. Sagar
