Thanks for the query.
Excessive blood flow with pain full cramps in periods can be seen in conditions like:
- Structural causes like fibroids, polyps, adenomyosis
also by increasing the local blood flow can lead to this condition.
-If there is any possibility of pregnancy, once rule out the possibility of miscarriage
-Usage of intra uterine contraceptive
If the pain and bleeding persists, once consult gynecologist and get examined.
If she recommends go for ultrasound.
Possibly with this workup the cause for your problem can be identified and treated.
