I came off the pills on March 10th, got the withdrawal bleeing on the 13th, and i got my first real periods on April 24th, (cycle 42 days long), and in my current cycle I'm on day 43rd and still no signs of periods. I had sex on May 3rd but he pulled, i have done three pregnancy tests, the last one i did was on June 3rd a whole month after and got negative. I have no symptoms of pregnancy then why am i so late this time?
