Hello,
After sex you are having odorless yellow discharge. It may be due to a change in the pH of the vagina. Soap in the vagina, spermicides or chemicals in the vaginal area,
hormonal changes, sexual activity or douching the area can cause the pH of the vagina to change, resulting in such discharge.
Avoid douching the vagina and take care of your hygiene. Other medical conditions that can cause such symptoms are
bacterial vaginosis (BV),
trichomoniasis, chlamydia,
gonorrhea, etc. Gonorrhea can cause white, yellow, or
green vaginal discharge. If left untreated it can cause
urinary tract infection symptoms or
bleeding between periods.
Trichomoniasis also causes yellow discharge, may cause frequent urge to urinate and if left untreated may cause swelling, redness and swelling of the vulva and the vagina. You are suggested to get clinically examined by a Gynae or health care provider. If you have yeast infection, you will be treated with an antifungal cream, ointment, tablet, or suppository.
Chlamydia and gonorrhea are detected by cell cultures obtained from vaginal or urethral swabs. Get STD tests done. If reports are positive, you will be treated with antibiotics and antivirals.
Take care. Hope I have answered your question. Let me know if I can assist you further.
