Hallow Dear,
Since you have taken Postinor pills within 72 hours of the sexual intercourse, you are protected from
pregnancy. In fact you have taken double dose of Postinor and hence you are feeling the symptoms like
dizziness,
nausea,
vomiting, etc. This is the effect of the Progestational medicine present in Postinor. It causes
gastritis with raised stomach acidity. Some
proton pump inhibitors like
Pantoprazole on empty stomach in the morning for few days will relieve you form this discomfort.
Postinor has few after effects:
1. Few days after their consumption, there is some bleeding, which is normal. You had such bleeding.
2. The following period may get delayed by few days to a week. You can wait patiently for the periods to appear.
Though he has not ejaculated inside your vagina, pre-ejaculation secretions (precum) are passed unknowingly. Precum does contain some sperms which can cause pregnancy. However, since you had taken Postinor, you are well protected. However, you should not practise withdrawal method for contraception; it is very unreliable method.
However, if the menses are delayed for more than 10 days, you may perform pregnancy test on overnight first morning urine sample for confirmation.
I hope this helps you.
Dr. Nishikant Shrotri
