My period is a month late. i've been having some brown discharge here and there but no actual blood flow and im bloated. is that a sign of pregnancy?

do a test: Only way to know is to do a pregnancy test.

Sexually active?: Reasons for missed/late periods: low body weight, obesity, marked weight ^ or v, over-exercise, endurance athletics, breast-feeding, ^ stress, illness, eating disorders (bulimia or anorexia), anovulatory cycle (no egg released), travel, hormone irregularities, drug use, meds (i.e., birth control) or medical problems. #1 reason is pregnancy. The best way to confirm one way or another is to do hpt.
