My period is late... it was suppose to arrive end of march, and still has not arrived. but when i was wiping after going to the bathroom, there was a little bit of red on the toilet paper, is that a sign that my period is coming?

With delayed menses, when previously "regular", obtain a serum HCG test to be certain about pregnancy. At age 32, and with additional stress (work, school, emotional) your ovulation may be delayed, which will delay onset of menstruation. Ask your gyn provider about low dose oral bcp's, which avoid the effects of stress on your menstrual cycle.
