thankyou for posting your question.
Your last Depo injection was in August and you`ve been noticing bleeding after intercourse
for one year now, paps were normal.
If your PAPs were okay, don`t worry. Postcoital bleeding or bleeding after intercourse is sannoying but usually nothing to worry about. You can have it treated though.
Women can have small bloof vessels that lie near to the surface of the cervix
and when during intercourse the penis rubs against the cervical surface these small vessels can open and bleed. So long as your PAPs are normal - It`s just annoying. But you can have this treated - the doctor will apply ice or a solutuion to the areas that bleed. This might have to be repeated a couple of times but you will usually have some peace for a while. The treatment doesn´t hurt - it`s just like having a PAP.
The lower abdominal apins shoudl be checked. You should also slowly be getting your cycles back and may be experiencing pain of ovulation - but just to be sure ask your doctor to exclude infections of the vagina (which can also cause postcoital bleeding ) and ovarian cysts.
All the best!
