Hello dear
I understand your concern
Touching of the finger to vagina does not cause
pregnancy.
To become pregnant penetrative sexual intercourse or intercourse up to vaginal intoitus is required in fertile phase of the period.
I do not think your act cause pregnancy as there is no penetration.
But delayed in period could be due to excessive
stress and
sleep deprivation,
hormonal imbalance and change in life style and dietary habit.
Wait for the period to come.
If period will delay by more than 14 days then go for urine pregnancy test and or blood HCG by consulting the gynecologist to confirm the cause
Meanwhile avoid stress, take healthy diet, drink plenty of water and do regular exercise.
Period can be induced by the
progesterone pill in absence of the period
Hope this may help you
Contact further if follow up needed
Best regards
Dr. Sagar
