First day of my last period was On 25th December, took prenancy today come out negative and now I have really bad cramps but doesn't really feel like period pains, why is this happening? :confused:

Take another test... or go to the doctors and they'll give you a blood and/or urine sample. Its possible the test was wrong. Or you may have taken the test too early. And in the case that you aren't pregnant, going to the doctors will still ease your mind because he/she will be able to tell you what your cramping might be. Better off to know for sure!

Oh, and if the cramps you are experiencing are similar to mentrual cramps but you come in shorter bursts and you can just tell they aren't period cramps, that's a sign of pregnancy in a lot of women. Just to give a heads up.

That's supposed to say "THEY come in shorter bursts" haha
