Posted on Fri, 11 Jul 2014
Question: Hi, i had sex with my wife on 12th XXXXXXX As it is unprotected sex she took idoz 72 pill. Her menstrual cycle should start on 19 XXXXXXX But she didn't get her periods till now(20 June). Is this the side effect of morning after pill or is she pregnant now. We don't want any babies right now. Do these pills cause any delay in regular periods, if so delay for how many days. She gets her periods regularly

Brief Answer:
Possible side effect

Detailed Answer:
Hello,
Morning after pill does cause irregular periods. You had sex around day 21 of your cycle. That should be safe enough. And out of the fertile phase. So pregnancy is unlikely. After taking the morning after pill, withdrawal bleeding can start anywhere from 2-14 days after taking it. This is a side effect and using the pill multiple times causes even more irregular cycles. Wait for spontaneous menses.

Thank you for your response. Am Mrs XXXXXXX I took this pill for the third time. It was more than a year when i took the pill for the last time. Does it cause any hormonal imbalance or irregularities in periods. We didn't had complete insertion into my vagina and also had the discharge outside. As i don't want to take the risk of getting pregnant i took the pill. Is there any chance of getting pregnancy. Plz explain me. Am very much tensed regarding this and was unable to pay attention in the office.

Brief Answer:
pregnancy unlikely

Detailed Answer:
Well, its not likely that you are pregnant. Esp since the ejaculation was outside.
You are possibly suffering from hormonal imbalance due to the pill. Wait for spontaneous menses to occur. Using the pill at long intervals is fine. But dont take them every month or multiple times at a stretch. That will cause irregular cycles and difficulty to concieve later.
