Hi there I had un protected sex on sat 25th jan and my last period was 29.12.2013 so was due on 27th jan I still haven't come on and its 4th feb could I be pregnant I've done a test and its negative please help x

Since it is too early to test, it is hard to say. Of course any sex ( even protected) can end in pregnancy. So of course you can be.

Wait till about the 11th of Feb. and do a test. Make sure it is first thing in the morning as soon as you wake up. First urine of the day
