Hi.
I've gone through your query. I can understand your 
anxiety. 
Abdominal cramps & heavy bleeding might be due to many conditions like 
endometriosis, fibroids, infections etc. 
-if your are of reproductive age group I would advice you to plan for 
pregnancy again 
- Hot compress in abdomen & back 
-Keep bowels empty
- Avoid food containing caffeine, alcohol 
-Encourage normal activities & 
YOGA - Cap. Meftalspas 1-1-1 for cramps 
- If not responding to the above line of treatment, underlying pathology if any should be rule out. So kindly do a USG pelvis 
- consult your gynaecologist for further assistance. 
Hope I have answered your query. Let me know if I can assist you further. Get well soon. 
Regards, 
Dr. Yogapriya V, General and family physician.
