Hallow Dear,
Contraceptive medicines are hormones containing Oestrogen and/or
Progesterone. These pills can prevent the
pregnancy if taken regularly throughout the cycle. Some high dosage emergency contraceptive pills may help preventing the pregnancy if taken within 72 hours of the
unprotected intercourse. However, these sorts of pills cannot terminate the pregnancy once the conception has occurred.
Primolut N is Progestational medicine and will not be useful to avoid pregnancy if conception has already occurred.
If you have missed your period, please get pregnancy test done on the overnight morning first urine sample after about a week of the missed period. Alternatively, you may opt for Beta hCG test on the blood to detect the pregnancy.
If you are not pregnant, some progestational medicine like Promult N or Deveri for 5 days will help you get the withdrawal bleeding.
However, if you are pregnant, Medical termination of pregnancy will help you terminate the pregnancy safely and effectively and within legal frame upto 7 weeks of pregnancy (if you are in India).
After the results of the pregnancy test(s), please report to your Gynaecologist without wasting time.
I hope this helps you.
Dr. Nishikant Shrotri
