Hello and welcome to HCM,
I am Dr Nilajkumar a consultant gynecologist and I will be helping you in your queries.
There are a few possible reasons for the bleed.
1. depo shot: they cause irregular periods
and usually cause absent menses. In some females however they may cause heavy bleeding.
2. Bleeding for scar site: rare. Associated with bleeding from the time of c section.
3. presence of placental tissue inside the uterus: retained bit of soft tissue
may cause heavy bleeding. They can be removed by a procedure called dilatation and curettage
of the pelvis is important as bits of tissue may be seen inside.
Do not worry as all the causes are treatable. Just see your doctor and get investigated for the cause.
Hope this was helpful.
Feel free to ask any further queries and I will be happy to help.
Thanks for using HCM.
Have a good day.
