Hello dear
I understand your concern
You have did sex when period was due, means around the period date.
It is very safe period and again you used protection without failure.
So chance of the
pregnancy is nil.
Now your period is delayed by the 7 days.
I would suggest to go for pregnancy test in next 2-3 days.
You can use prega news or I can pregnancy kit.
But I think it will come negative as you have did sex in safe period with protection.
Your period could be delayed due to
hormonal imbalance,
ovarian dysfunction.
If period will not come then meet the gynecologist to find out the cause.
Period can be induced by the
Progesterone pill in absence of the pregnancy.
Avoid
stress, take healthy diet, drink plenty of water, maintain proper pelvic hygiene, and do regualr exercise.
Hope this may help you
