Something blocked my vagina

I’m 22 years old female. I’m virgin and no sex experience before. Recently my vaginal discharge smelled badly and I went to see the clinic doctor and he said it might be due to bacterial infections and gave me antibiotics without observing my private part. After eating medicine, my vaginal discharge smells better. However, when I check my private part, I found that there is always some white colour thing on my outter part of vagina and I also found the opening of the vagina got two pieces of meat, blocking the hole of vagina(I can’t express well, it is like something blocking my vagina and I can’t look into the vagina). Is it possible that it is actually hymen but hymen should be a thin membrane but the two pieces of meat look thick and can be obviously seen. What happen to my vagina, pls advice.
