I feel so humiliated and embarrassed

So I had my women’s wellness today and when I got to the clinic I had something else I needed to discuss with the doctor. I told her I had taken a plan b last month and my period was really weird. Well she told me that we needed to get through the Pap smear and then we’d find out what’s going on. Well she’s doing the Pap smear and tells me there’s an issue and then the most embarrassing thing ever happen to me. She pulls out a tampon that has been there for about maybe a week. It smelled so bad and the doctor immediately left the room. She made everything else she said to me very short and acted so rude after that happened. I just wish she could’ve been a little nicer because honestly I feel disgusted with myself and humiliated and embarrassed just really unhappy now. I know I probably deserve to feel this way but I was wondering if anyone else has ever gone through this so I don’t feel too bad. Thanks.
