I have very regular periods ranging from 5-6 days and I used to have heavy bleeding in my first 3 days ever since I started menstruating. From last 2 months (without any major lifestyle change or birth control) the amount of bleeding has reduced drastically. Previously lets say I used 3-4 pad changes in a day now I can do with 2... should I be concerned ? I do plan to have kids in a year or so hence want to make sure if I should be concerned
