4 days late, light spotting 2 weeks back, white discharge now and light cramping, could i be pregnant?

Maybe, maybe not...: Pregnancy is the most common cause of a missed period. If not pregnant, other causes of a late or missed period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (especially birth control pills), hormonal disorders, etc… can do a pregnancy test later this week. Can see the ob-gyn if symptoms are persistent or worrisome.
