Pessarys causing more pain

I've got thrush and BV and I'm on night 4 out of 14 with my pessarys and honestly I'm in more pain down below than when I was before I started these... and I have a horrible stiff pain at the top of my vagina on the left side. Is this normal? Or could this be due to tensing when inserting the pessary? In so much pain with it and down below in general and at the moment the pessarys are making it worse 😭😭
