2 day before to that day to 1 day after that day.... Is best time

I want to give the general opinion and not like a doctor and see everybody knows that conceiving is a natural process after the marriage. Following the periods and following the dates and following the timings leads to anxious and stress which may lead to failure in the conceiving. Your age is around 21 years and it is better to to go through naturally without any expecting that will going to conceive. We are falling all these things but look at our elders they are not going to do anything but had the children. Coming to the specific reason to consult the gynecologist and go through the clinical examination in detail.

14th day(double line ) is fertile day. Keep relations with husband on this day and 1-2 days +/-
