The date of period was on 1st july. But it dosent come till today 5th august. In last month (july)  we have chaked it 3 times with prega kitt, pregnency report was negative. She has taken the medicines (7days captuals for bringing period) which was given to her for missing period earlier by a gynologist. But that also not worked. What should we do, we will contact to a dr in a week but till that plz give some suggestion what is happening.?
