Welcome to Healthcare-Magic
Greetings of the day
Its unlikely that you are pregnant, as it was during the safe period you had sex.
In a 34 day cycle the ovulation usually occurs on 20th day of the cycle and you had sex on 24th day onwards, probability of pregnancy
is less likely.
Do repeat a test again.
Be relaxed and let the nature decide when you get period in case you are against taking ocp
In case you need any further assistance, will be glad to assist you.
Wishing you happy and healthy life
