Hello dear
I understand your concern
yes, female actually can get pregnant even if she is virgin.
If sperm gets on near to vaginal introitus, it can swim up there and cause pregnancy
But it also depend on the amount/concentration of sperm and day of the period when did you sex.
But you have to think about pregnancy when period was delayed by the the 8-10 days from the normal expected period date.
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.
Meanwhile avoid sex, take healthy diet, drink plenty of water and do regualr exercise
Hope this may help you
Best regards
Dr. Sagar
