instruction: hello doctor I had unprotected sex last march but took emergency contraceptive afterward six days after I had the bleeding associated with the emergency contraceptive two weeks after that in the first week of april I had my period for six days my usual period lasts five to seven days in may I had five days of the period although the last two days were only very light bleeding now I was due for my period four days ago but I still have not got it what are the chances that I am pregnant and if not should I be worried about my late period
output: hello firstly as you had three episodes of menstrual bleed including the withdrawal bleed post emergency contraceptive after you had intercourse in march so it is unlikely that you would be pregnant due to your sexual encounter in march as you have missed your menses now by four days and if you have been sexually active during this cycle as well then you must rule out pregnancy first with a home urine pregnancy test kit if negative then the delay is most likely stress induced and you should wait for at least five days to allow menses to start naturally if not then you would need an ultrasound pelvis to check for endometrial thickness which if more than my you can be offered a withdrawal bleed with progesterone to resume your menses
