HELP!!! 😭😭😭

My OB prescribed to me Albothyl because she saw a minor abrasion inside my vagina. It's suppository so I put it inside last night. Tonight, I saw a weird white thing poking out of my vagina. I tried to pull it out but I was only able to get the end of it (it got separated). It felt like it was long and elastic. I tried to pull it out again, this time I tried to hold on to a bigger part and pulled harder. But as I pulled, it hurt inside. Like somehow it stuck to a part inside me so I stopped.

I'm really so worried what this is. :((( I looked at it again and it's gone. I called up my OB's secretary and she said it was normal but she didn't seem too sure and she said she'll tell the doctor tomorrow (since it's nighttime here). Is this normal? It really didn't look and feel normal though?
