Hello
Thanks for writing to us with your health concern.
When taken within 24 hours of unprotected sex, an ECP ( emergency contraceptive pill ) is more than 95 % effective in preventing a pregnancy.
So you are reasonably protected against pregnancy.
There is no point in repeating the ECP again.
For 120 hours, there is no logic in repeating the dose.
The earlier pill keeps you covered and further dosing ( you have already taken 2 ) will reduce the efficacy.
The pregnancy test should be taken 4 weeks after the encounter of unprotected sex, not earlier.
Only then would it give a conclusive result.
Repeated, random, casual and frequent use of ECP will mess up the normal menstrual cycle.
It can prepone or postpone your periods indefinitely, and there would be unpredictable withdrawal bleeding anytime.
ALso, the efficacy is lost with repeated usage.
Always make sure to have protected sex.
All the best.
Take care.
