1. Light flow
Most pills wreak havoc in our bodies, so if you’re on a pill then your light flow will be justified. However, if not then it might indicate a pituitary or thyroid problem.
2. Sudden bleeding
Periods usually begin with light spotting and then move on to the heavier flow. However if you experience sudden heavy bleeding then it is never a good sign.
3. Unbearable cramps
Cramps are normal as your lining inside breaks. However if they get unbearable and do not get under control even after medication then it may be a sign of something bigger.
4. Abnormal or late periods.
Weather pattern changes period pattern. So slight delay in winters is normal. But if it gets really delayed without any reasons then you should probably take it seriously.
5. Saturated color
Of course, it is going to be darker than your average blood color. But it shouldn’t be darker than cranberry juice. If it is darker than that then it may indicate to an estrogen imbalance.
