Thank you for your query at DoctorSpring.com
Kindly clear my doubts first.
You had taken one plan b on may 6th, following which you got your period. Now for this present cycle, your period is 10 days late. Did you have unprotected sex after your period in the month of may? Yes, stress does affect the cycles. I need to know your sexual history before I can comment on pregnancy status. If there has been no intercourse after the period on the month of may, there is no question of pregnancy.
Feel free to discuss further,
Patient replied :
I have had protected sex since and I have made sure that all the condoms remained intact.
You will definitely get your period in that case.
There is no question of pregnancy when there is no unprotected intercourse.
Periods can get delayed because of hormonal fluctuations, stress, e.t.c
