I had my last period on about 22nd of dec. Then I had intercourse between 28 th dec and 4th jan almost regularly but with condoms. Then as my periods did not come by 17th jan I did a pregnancy test which was negative. Then we again had sex between 17th till 24th of jan again always with condoms. I had an ipill on 24th night as I was scared of not getting my periods. I did a pregnancy test todayi.e. on 28th jan and it is negative. I still did not get my periods. Am I pregnant? Please help

You have to be almost 2 week late for a pregnancy test to show properly. So your tests were way to early.

Also the I pill is only good for max of 72 hours before it was taken, so not all sexual activity is covered. It is also, less and less effective the longer time it takes after sexual contact.

So it may be lets say 99 percent effect first 10 hours, but toward the 70th hours after sex, it may only be 40 or 50 percent. (or less)

The I pill has a side effect of causing cycle, or sometimes stopping it for a month or two.

You need to wait and see if you get your period and if two week late, do pregnancy test. Always do the test first thing in morning as soon as you wake up

If you had protected sex and also took I-pill then chances of pregnancy is very low. If you do not get periods by the next week then you should probably visit your gynec and check what went wrong. Pregnancy is detected only after 3-4 weeks from intercourse.
