Irregular periods, weight gain, constipation and itchiness may indicate a medical condition. One should seek the help of a gynecologist in cases where periods are not on regularity and that of a gastroenterologist when one is having constipation. A dermatologist should be consulted for weight gain and an endocrinologist, on the other hand, in case of itchiness. Do not dismiss these symptoms as a failure to diagnose and treat correctly may diminish your physical health and happiness.

Noticing brown blood clots in your urine during pregnancy can be worrying. It might be a sign of a threatened miscarriage, which can cause bleeding and clots. It's good that the bleeding has stopped, but please stay alert and talk to your obstetrician to discuss your condition and get the right treatment.
