Hi,

Thanks for posting your query

Pregnancy can occur due to vaginal penetration as sperms can travel through vagina even if ejaculation was not there and if precum was present as it contains sperms.

In a regular 28 to 30 days cycle duration the ovulation days(most fertile days)are 9 to 16 days of the cycle considering day 1 as the starting day of period.

Though the chances of pregnancy are rare but it is advisable to take an Emergency Contraceptive pill for protection from pregnancy.

You can also do a urine pregnancy test after a month.

Consider using different contraceptive methods as condom,pills,IUD etc for regular use .

Hope this answers your query.I will be available for follow up if any.

Hi,

Thanks for the follow up query.

The chances of pregnancy are less but since he had erection before so possibility of precum being present is high.

Even if the penetration was for short duration, if sperms would have been there they can easily swim towards vagina. So it is advisable to take Emergency pill.

Regarding the side effects, the common ones are nausea, vomiting, breakthrough bleeding and delayed next period(about a week or so).

The irregularity in periods suggests hormonal imbalance and if there has been a sudden change in your cycles it requires a complete evaluation and should not be ignored.

In case you are lactating then some changes in cycle can be expected.

Best option at this time would be to take Emergency pill and wait for a month for your periods to happen.

If not, Do an Urine pregnancy test.

Hope this helps!

Regards,
