Brief Answer:
Pregnancy unlikely.

Detailed Answer:
Hi,

Thanks for posting your query.

In the manner in which you interacted, pregnancy is unlikely.

Ovulation happens around two weeks before the onset of the next period and this is the fertile period when conception can occur. Pregnancy does not happen at the time of a menstrual period, which is absolutely safe.

Emergency contraception can often delay a natural cycle owing to the high hormone content in it. Even though withdrawal bleeding may not be seen after consumption of the emergency pill, the next natural period may still be delayed by a week or two. Added to this, the stress that you perhaps have about getting pregnant also may have contributed to this delay.

If you do not see your period, even after ten days after it is due, please see a specialist for further evaluation. In the future, please use a regular form of contraception and restrict the use of emergency pills to once or twice a year.

Hope your query has been clarified. Please feel free to contact for further information. I will be happy to help.

Answered by Dr. Shanti Vennam (6 minutes later)
Brief Answer:
Mostly not needed.

Detailed Answer:
Hello,

Thanks for writing back.

Home pregnancy tests have a very good reliability if performed as per the precautions mentioned, i.e., done with a fresh early morning sample of urine 3-7 days after a missed cycle when no hormones have been used.

It is mostly not required in your case since the day you had the incident was absolutely safe.

doctor
Answered by Dr. Shanti Vennam (5 hours later)
Brief Answer:
Can try induction after sonogram and blood test.

Detailed Answer:
Hello,

Thanks for writing again.

Of course, a period can be induced by using a short course of hormones after excluding pregnancy and other possible causes for the delay through a blood test for pregnancy, trans-vaginal sonogram and a hormone profile if needed. Withdrawal bleeding is attained 3-7 days after completion of the treatment.

Hope your query has been answered. Please contact if you need any more information. I will be available to help.

Is it required in my case? Is there any chance I will miss my periods totally?
doctor
Answered by Dr. Shanti Vennam (1 hour later)
Brief Answer:
Not necessary.

Detailed Answer:
Hi,

Thanks for writing back.

Forcing a period is not necessary unless you fail to get a period even after two weeks after the due date. It is highly unlikely that you are going to miss your periods forever. Please do not stress as this can also cause delayed periods.

Hope all your queries have been answered. Please contact if you need any further information. I will be glad to help.

Brief Answer:
Period delayed due to high hormone dose.

Detailed Answer:
Hi,

Thanks for writing back.

Emergency pills, as I mentioned earlier, contain excess dose of hormone so as to get quick effect and this in turn can lead to onset of withdrawal bleeding most of the times and even if this cannot be seen, can result in a delayed period mostly.

Thus, periods can get delayed up to two weeks. It is highly possible that you may see your periods within the next week. You may not get any indication of a period as ovulation may have been aberrant in this cycle.

Hope your query has been answered. Please get back if you need more help. I will be happy to oblige.

Shanti.V.
