I took the 72 hr pill right after I had sex... seven days later I took the pregnancy test; I got a negative result... then the following day I tested again and got a positive result the second time, I tested again and got a negaive test and the forth time I got a positive result... I m having cramps but not severe ones... I m scared to test aagain... I am a day late

If you're a day late do another test , negative results are less accurate than a positive. Or go to your doctor to be certain. Good luck

How long ago was the unprotected sex? Are you using first morning urine? Are you reading the results within the time limit on the box?

My last period was on the 8th of oct and ended on the 12th... I had unprotected sex on 21-23 used plan be on the 22nd... I tested negative on 29th of October and positive on the 30th in the morning and later tested negative that same day... then the following day I tested positve... my cycle is 28days... I m having virginal discharge (milky) the one you get while ovulating...

If you tested positive you probably are. Go to your doc and get blood work done.

It is honestly too early to test positive for a pregnancy test of you had unprotected sex on the 21-23 of October. Over-the-counter HPTs typically do not detect pregnancy until at LEAST 4 weeks pregnant. You may be getting a false positive due to the 72 hour pill.

But to be sure, you should make a doctor's appointment because the 72 hour pill is not always effective.
