Patient's Query

Hello doctor,

Emergency contraception is 95 % effective, mean is there some chance of getting pregnant? Please tell me;

  1. What more precautions could be taken during sex so that there will be full certainty about it?
  2. After taking it, will the periods be painful?
  3. In what way will it alter periods?
  4. Will it change the number of days of the period? And
  5. What is withdrawal bleeding?
  6. Will it be there immediately after taking it? Or after a day or two?
  7. When will it be 100 % effective?
  8. Is there any other way to avoid pregnancy completely in unprotected sex?

Hi,

Welcome to icliniq.com.

I have read and understood your problem.

Yes, there is some chance of pregnancy. You can use a condom, but there is no contraception that is 100% effective; even after a contraceptive operation, a very small chance of pregnancy remains. You can bleed any day after taking the I-pill.

There is no fixed rule; it may take even 10 days, and bleeding usually will be normal, not painful. When bleeding occurs after stopping the pill, it is called withdrawal bleeding. Withdrawal bleeding rules out pregnancy. However, your next period may come early or late, so take precautions with adequate contraception.

Contraceptive pills can change your bleeding amount and cycle for one or two months. It will be effective only after sex, not before sex. But, as mentioned above, there is no 100 % effective method.

Patient's Query

Hello doctor,

Will withdrawal bleeding ensure that no more chances of pregnancy? Or when will we be completely sure that there are no more chances of pregnancy?

May I know the way that will prevent pregnancy completely?

Kindly help.

Hi,

Welcome back to icliniq.com.

If the amount of bleeding is good, then it rules out pregnancy. Two negative pregnancy tests on the 7th and 14th day after your expected date of period rule out pregnancy. As mentioned before, there are no 100 % effective methods. But regular oral contraceptive pills have the best success rates.
