I had unprotected sex with my partner before 60 days back. I had pill 72 immediately 4 -5 hours after having sex and I took another tablet after 12 hours. I got my period after 3 days of taking pill 72 and last for 4 days. But then after I missed my period and haven’t arrived yet.
My menstrual cycle was very much regular but this time I haven’t got my periods yet.
I have taken pregnancy test twice thro pregnancy test kit and both the test was negative.
But I am afraid that I would not have been pregnant? Because I am not getting my periods?
Does it really happen that I got my periods late because of pill 72?
When will I expect my periods again? Is there any chances being pregnant ? Shall I wait for my periods or take other medicines ? Suggest me.

You are probably not pregnant unless you have had another risk since then and now (any intercourse is a pregnancy risk). Most likely the pill messed with your hormones and you should probably visit the doctor if your period does not come soon.
