Why Menstrual Clots Matter — When to Watch, When Not to Worry Seeing clots during your period can be normal, but not always.

However, large or frequent clots may signal conditions like fibroids, hormonal imbalance, or anemia. Tracking your cycle helps doctors identify patterns early and prevent complications. #hospital #NMC #healthcare #healthcare tips
