some symptoms ive been having..am i pregnant?

okay well...4 days ago i woke up with acne ALL OVER my face..which is not normal for me AT ALL...i usually only get one or two when i start my period, thats all....but this has never happened before.

and ive been having these lil cramps...but they last a couple seconds..and ive had this white discharge..its not "stretchy" like ovulation discharge..

and ive been so moody lately...to the point where me and my boyfriend get in huge arguements =\

i would wait til i miss my period to take a test..but my periods are so irregular..i never know when theyre going to come.

try charting your cycle on the below site.. it's free and will help you work out your pattern. you can go back to prev months and entre your period dates if you know them...

also if you think you may be overdue, do a home test just to check.
