for the last few months...starting at least in September i get my period for 5 days and then 2 and a half weeks go by and i get my period again....normally like 2 weeks and three days...anyway.....im on coming up on my 4th week this sunday.....is this normal??? I have been sexually active.....i am confused perhaps im just stressed.....can a period be missed all together because of stress? Or does it eventually come....I told my x that if i dont get my period by this tuesday (it will be 4 weeks and two days then) i will get a pregnancy test.....otherwise..i am trying not to worry about it.........
