Hi there, I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
Please seek prescription support from your treating doctor for a broad spectrum antibiotic like Doxycycline 2 times a day for a week. This helps to clear most of the sexually transmitted diseases.
The discharge after inserting
vaginal tablets can be due to dissolved medicine or the capsule covering that comes out. So do not worry about it.
I will suggest you to get per vaginal and per speculum gynecological examination done to rule out any pathology like
cervical polyp or erosion, that can cause bleeding off and on, and any element of
pelvic inflammatory disease.
I will strongly suggest you to get sex counseling done before going ahead. This will help you to know about safe and protected sex, and will help prevent unwanted
pregnancy and STDs.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar
