Two weeks ago friend and i hook up. we didn't use a condom and i'm not on the pill. so the my lady part is dry and itchy and period is late.

Some thoughts...: 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 hormone or birth control pills), hormonal disorders, etc… A visit to one’s Ob-Gyn doctor is a good idea if symptoms are persistent or worrisome.
