Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
Yes intake of Ipill could cause delay in periods for weeks. Delay in periods is a common side-effect after intake of an
emergency contraceptive pill like I-pill. The delayed periods are due to effect of high dose of
levonorgestrel hormone in I pill which disrupts your normal
menstruation & causes delayed periods. Your periods may be delayed for 1-2 cycles.
As you had taken the emergency contraceptive pill within 24 hours of sexual intercourse,
pregnancy possibility should be very less. The
abdominal bloating or feeling tensed you are facing should be as a result of stress of getting pregnancy, it is not sign of pregnancy. Also pregnancy possibility is often less on last days of cycle. Altogether pregnancy chances should be negligible in you
An emergency contraceptive should not be used as regular method of
contraception. Regular intake of emergency contraceptive pill could cause irregular & delayed periods & other harmful effects including
infertility. Next time use regular contraceptive pill or condoms for prevention of unwanted pregnancy.
You are also advised to do a pregnancy test to rule-out even slightest chance of pregnancy.
Don't worry you would be fine
Hope this information helps
