We had unprotected sex 21st of march... then she has his period on 29th march. Her periods are normal. But now she does not has his periods yet.. what's wrong.. can any one tell me please

Her period may just be late, or she may even skip a month. Give it a bit more time, if still no period, she can always try a pregnancy test.

If pregnancy is not part of the plan at this time, do not have unprotected sex. Even with proper birth control, pregnancy may still happen but the chance will be reduced. If any chance of pregnancy is too great, stop having sex until the possibility of an unplanned pregnancy would not be a concern.

She could have course very well be pregnant, but she is only 4 days late, (which is not really that late) So for now, she waits, when she is 2 week late she can test with the first urine of the morning, when she wakes up.

It can be infections, it can be other illness, or even just a late period, even stress from worry about pregnancy.

Now you just wait.
