If there is one dark line between C and T on the test, it may mean a negative result since T indicates positive. But it should be taken into consideration that wrong tests may appear and more test is required. If you are concerned about your pregnancy condition, it is best to see a doctor

Weight gain could be the reason for your heavy periods. It can lead to hormonal changes, increasing blood volume and resulting in heavier periods. This happens because fat cells produce estrogen, which affects the menstrual cycle. To help regulate your periods, try maintaining a healthy weight by incorporating a balanced diet and regular exercise into your routine.

If you are not getting your period, several reasons might contribute to stress, change in weight, or hormonal imbalance. This condition may be regular, but it should not be treated lightly. To decrease the worries that exist at home, you can seek advice from a local health center or a doctor. They will discuss your condition thoroughly and can perform the proper tests. No need to be anxious; you will feel better with the help of a specialist.
