Hello,
I do not understand what you meant by side effects. If you are expecting some external evidence to suggest that the pill has been effective in avoiding a pregnancy, please understand that no such obvious effects are immediately seen; it is a silent process that works inside your body. Since you have taken the pill within the stipulated time interval, you are amply protected and as such, there is no need to consume another one. Also, please keep in mind that recurrent pill usage can harm your hormonal balance immensely. If you are in your safe period, you do not need the pill at all. Hope this helps.

Hi,
You need not get worried.
You have done the right thing by taking i pill within 24 hours of unprotected sex. I pill is very effective in avoiding pregnancy ( 95%). There is no need to take the second i pill tablet. I pill may cause side effects like nausea, vomiting, breast tenderness in some. It does not cause immediate bleeding.
If you have taken the pill in the first half of your menstrual cycle it may cause your periods to occur few days early. If you have taken it in the second half of your menstrual cycle, it may postpone your periods by few days.

However (since it is not 100% effective) there is a small possibility of pregnancy occurring due to method failure. Therefore if your period is delayed by more than a week get a pregnancy test done.

To avoid such unnecessary stress I advise you to consult your doctor and start regular contraception like hormonal contraception or have an intrauterine devise fitted as they are more effective than i pill in preventing pregnancy.

I hope I have answered to your satisfaction.
