Ok I've been spotting for about a week now on and off then today I finally started bleeding a little heavier but its more like blood clots and it only comes down when I pee or whipe myself up... it really doesn't get on my pad just a little.what does that mean am I preganat or is it that my period is just changing?! Please help!

Could be either one or neither. There are a number of possible reasons for irregular bleeding. If you think pregnancy is possible, try a pregnancy test.

If negative, see what happens when your next period would be due. If it is still off from your norm, best to see your doctor for another pregnancy test or to determine another cause.
