Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... I-pill is an emergency contraceptive pill & it contains levonorgestrel hormone which could be used as a contraceptive agent after the intercourse. According to your query you have gotten pregnant despite taking I-pill. No, levonorgestrel contained in i-pill will not harm or cause any defect to your baby as you have got pregnant while on I pill. Levonorgestrel has been checked thoroughly as emergency contraceptive & there was no correlation found in childs who were conceived when levonorgestrel was taken as an emergency contraceptive. It also has short half life so it is rapidly excreted out of body. So as you have got pregnant, you could continue the pregnant or get an abortion done. It is up-to you only to decide. You should also undergo ultrasound tests as suggested under guidance of your gynaecologist, if you want to continue this pregnancy. Refer to your gynaecologist Hope this information helps
