Hello dear
I understand your concern
There is always some chance of
pregnancy in the unprotected sexual intercourse, pregnancy can be possible by ejaculating around the vagina.
Following are the symptoms of pregnancy:
Most common: missed period
Variable: heaviness,
fatigue,
dizziness, nausea, light spotting /bleeding for 1 day 10-12 days after
implantation, breast and areola enlargement, darkening of areola.
I pill will not help as 72 hour has been crossed.
I advise you to now wait for period only.
If period is delayed by the 8-10 days from the normal expected period date then go for pregnancy test and blood HCG to confirm the pregnancy.
If pregnancy will be there, still you can terminate the intrauterine pregnancy by
abortion pill under the advise of gynecologist.
Avoid stress, do regular exercise and take healthy diet.
Hope this may help you
