Hello,
Thanks for the query to H.C.M. Forum.
Discharge or bleeding ( very mild ) may be due to masturbating ( forceful).
The other reason of discharge may be
pelvic inflammatory disease.
In my opinion consult a Gynaecologist and get his opinion as physical examination is very important in this case.
Ultrasound may help you as for irregular bleeding.
Good luck.
Dr. HET
