Since how many days you have bleeding after period?
Are you taking any medications ?
Are you sexually active?
Age ? Is it bleeding or just spotting?
Considering your symptoms it can be due to variety of causes like hormonal imbalance , endometriosis, DUB , uterine fibroids, Polyp ,malignancy ,to name a few .
In my opinion you need a Pelvic examination to assess the condition of the cervix and investigations like TVS Ultrasound for further evaluation .
Please see Gynecologist for evaluation and management.
