hi.. i have never had sex, but i hv done till fingering and insertion for a second or so in the past 3 months. my periods have always been normal. but last month they were 10 days late. i had them on 24th may instead of 14th, n this month till nw i didnt have my periods.. i want to know the exact cause for this delayed menstrual cycle.. is it because of the physical relation which i have with my boyfriend from past few months?????? can insertion or touching of penis cause pregnancy??
