Hello, You are feeling like something is stuck in your vagina and will not come out. It gives you discomfort. You have history of having PCOS. You have not mentioned if you feel it while having sex. It needs evaluation, get PCOS treated. Get clinically examined by your gynecologist to detect cervical polyp, cyst, uterine prolapse, bladder prolapse, etc. In case it is lax pelvic muscles that are causing symptoms, you can do Kegel exercises to help strength your pelvic muscles and keep it tight. Bladder prolapse may cause urinary frequency, frequent bladder infections, pain with intercourse. Uterine prolapse if neglected may cause infection in the cervix, get it treated. Get urinalysis (R/E and C/S) done to detect UTI, as it may also cause stinging discomfort. If positive you will be treated accordingly. If sexually active, get STD tests done. If reports come 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.
