I took emergency contraceptives and had bleeding during my ovulation but now im late on my period. i have irregular cycle?

Home Preg Test: Best to do home pregnancy test on first morning urine. If neg, repeat in 7-10 days. If both neg, unlikely you are pregnant. Emergency contraception can mess up your menstrual cycle. If preg tests neg, wait until next cycle should start. If no period within a week of when is should start, see your gyn provider. Hope this was helpful. Best of luck. Dr R
