Thank you for your question.
I am Dr Saha, I shall try my best to help you.
Most STD usually appear before 3 months.
Some can be delayed.
It can be a separate infection.
However as you have symptoms, you should discuss with your doctor.
After physical examination doctor can order relevant tests to know the cause.
As your partner has fever, stomach pain, she should be checked by doctor.
After preliminary evaluation, doctor will do lab tests and decide whether it is related to STD or not.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
