I had to take the morning after pill on the 22nd of may i had sex on the 19th bleed on the 29th now i'm 6 days late how bad does it affect ur period?

Typical with Plan B: Plan b essentially disrupts the normal menstrual cycle by blocking or delaying ovulation. That it is how it works and why it is so different than a medical abortion. Irregular bleeding after taking Plan B is not rare. Always check a pregnancy test after using Plan B and see a doctor for birth control. You may not know if it's Plan B bleeding or your cycle because the cycle was disrupted.

See your provider: When you take the morning after pill, it is Progesterone and kind of flushes your lining and brings on a period. This can effect the timing of your next period. Please see your provider to discuss a better method of birth control. And do a first morning pregnancy test just to be sure. Morning after pill is not 100% effective
