Hello doctor, I am having irregular periods and thyroid but thyroid is under control and from last 4 month's periods became regular, may month I got period on 4 in this june month I didn't get periods after 25 days I pregnancy test kit but result was negative what would be the reason. This time I thought I might be pregnant with so many hope's but disappointed shall I continue test again after some day's or should consult doctor and do beta hcg test. Once clarify me if in kit if it's negative means not pregnant only or should consult doctor. For further one. Or else pregnancy test shows negative if pregnancy is there will it happens like that.
